As you can notice
Symbols are been correctly loaded.
I just created a view GetCompanies.cshtml using the AddView shortlink
But, no matter what I do, I can't debug in the View.
What I did so far:
Close and Open Solution
Close and open Visual Studio
Shutdown all ASP.NET Development Server's
Deleted all Symbol Libraries .pdb
Clean Solution
Re-Build Solution
did not (yet) shutdown Windows 7 x64 :-/
Sometimes if you have a hard stop, Visual Studio temp cache will be screwed.
Clear the cache by deleting these folders:
C:\Windows\Microsoft.NET\Framework\<.net version>\Temporary ASP.NET Files\(ApplicationName)
C:\Windows\Microsoft.NET\Framework64\<.net version>\Temporary ASP.NET Files\(ApplicationName)
I am finding the same behavior from time to time when debugging silverlight. My solution is to clean the browser's cache (on latest IE click on the wheel button, Developer tools), as it sometimes will cache the binary files and not load the new ones.
Perhaps is could be the same with your views?
Been messing with this problem for a couple hours trying everything above. I finally changed my Target Framework to .NET Framework4.5 and it all started magically working.
This is always weird. I just had this problem and solved it with a full rebuild of the entire solution.
There was also another strange symptom, though: a new unit test that I had written using NUnit, mocking with NSubstitute, wouldn't pass because NSubstitute wasn't returning what I wanted it to return. I lost a few minutes trying to figure out if I did something wrong programming NSubstitute, then when I tried to attach the debugger to the NUnit GUI I saw that warning.
That's when I decided to do a full rebuild of the solution, and that worked for me.
So I guess the lesson to be learned is "before smashing your head against the wall, try a full rebuild".
For me, I somehow switched my target build to Release instead of Debug
Remember that views are actually compiled when you request the page (by default).
This means when you set a breakpoint in a view:
It shows the "No Symbols" error. This just means the view isn't
compiled yet.
It shows the breakpoint fine. This just means
that it found SOME compiled version of the page. Like the LAST working version...
So basically its not meaningful information to look at what it says when you mouseover the breakpoint in a view (at least in this regard)
If you are trying to debug this page, then you have a problem. Look at what the debugger is outputting to your BROWSER instead and fix that first. I think we'll be surprised about how many people are going to facepalm at this.
I had this problem with SL5 project (VS2012). And to fix this, I was needed to set "Silverlight" option enabled in %MyProjectName%.Web project properties, under Web tab.
In my case, the .PDB file was hosed (from which the symbols are loaded) in VS 2012, so performing a Clean and Build reconstructed the .PDB file and everything started workign again.
I was attempting to debug a deployed WCF windows services (compiled in Release mode) and had the exact same issue. Give this a shot...
Save All. You may even want to try to clean the solution
Rebuild all and install or deploy
BEFORE starting the service (or exe) I copied the .pdb files over to the install folder
Start the service (or exe) and attach the debugger to the process
Worked like a charm (finally) for me.
delete bin and obj directories
run solution again.
Note: Unless that cshtml loads at runtime the symbols are not loaded. On page load that breakpoint will be hit. So wait till control goes to that page
I'm unable to debug a WinForms C# application using the released version of Visual Studio 2010 Prof.
I get the following error message after the second debugging run.
Error 9 Unable to copy file "obj\x86\Debug\Arrowgrass Reports.exe" to "bin\Debug\Arrowgrass Reports.exe". The process cannot access the file 'bin\Debug\Arrowgrass Reports.exe' because it is being used by another process.
I've tried a pre-build script to attempt to delete this file, but it's locked by Visual Studio.
There are a few references to this on the net so it is a know problem. Does anyone have a hotfix or effective work-around?
I have found this issue very easy to reproduce, and the fix for me is a variation on Richard Fors' answer. If I have a UserControl open in the designer, run the debugger, and then edit the UserControl, the subsequent rebuild will fail. If I close the UserControl before running the debugger I never get this error, so I just make sure to close the designer window before hitting F5.
As of October 2012, I still have that issue so the VS 2010 SP1 didn't solve the problem. What I did, and worked consistently, was disabling the hosting process in the projects.
To disable the hosting process:
. Open a project in Visual Studio.
. On the Project menu, click Properties.
. Click the Debug tab.
. Clear the Enable the Visual Studio hosting process check box.
Source:
http://msdn.microsoft.com/en-us/library/ms185330(v=vs.100).aspx
You can try to kill the vshost.exe process:
taskkill /F /IM "Arrowgrass Reports.vshosts.exe"
You might also be lucky and simply be able to move the file in question. Moving the file can be done by adding the following lines of code to the pre-build event of your project:
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
Disabling windows search did not fix for me. However disabling Antivirus did (our Antivirus is Symantec Endpoint Protection 11)
As such, I was able to fix this for myself by changing the Debug settings in the project to point the working folder to a path on the C: drive, and then excepting that path from the antivirus auto-protect scan settings.
I hope this helps someone.
I posted this answer in a similar question but figured I'd also say it here:
Alright... this might sound pretty crazy.
I've had this problem in VS2010 for the last couple of years. The workaround mentioned here works for me, but a lot of times I forgot to close all my forms/usercontrols first.
I've discovered that merely going to view the open files via:
Computer Management (compmgmt.msc)->Shared Folders->Open Files
will "Free up" whichever file is being locked. Very strange, but it works for me!
In my case, I did Project Properties-->Security Tab-->Uncheck Click-Once security settings (If it is checked). It worked for me. In my project, it was showing this error for a C++ dll being used in my C# project.
The condition described can also be caused by the offending DLL or EXE referencing itself; in which case the Process Explorer test described previously never returns a match (e.g. it's not running). This unexpected situation seems to be caused during some sequence of operations in VS2010 (and likely all previous versions) which insidiously adds the reference behind the scenes. The specific cause of this hasn't been tracked down (or resolved that I know of). To check for, and resolve this error simply make sure the offending DLL or EXE is not listed as a reference to itself.
Got the error ("The process cannot access the file … because it is being used by another process") when I modified the (Visual Studio 2010 C# Express with SP1) solution from two large (10 source files, ~500 lines per file) projects with one referencing the other, to lots (6) of smaller projects with lots of projects referencing other projects.
The references were to the dll- and exe files (the Debug versions of them), NOT to the projects even though the projects were in the same solution.
I then learned that references should be to projects, not files, for F12 to work properly. So I modified the references. That made F12 work (jump to the source file instead of some auto-generated interface description), and at the same time the "cannot access file" error during build disappeared.
I only got the "cannot access file" error when doing Release builds. The references were to the Debug versions of exe/dll's. I suspect that this mixing is what triggers the bug in VS.
I encountered this issue when developing windows services. I found out that it happens when the service is running. Thus, you only need to stop the service (from the services.msc console) and you're good to go !
Hope this helps.
Tidjani.
Check Task Manager for the specified process and End the process explicitly. This solution worked for me.
I cant' write to a comment since not at 50 points but for me I excluded my project folder in ESET Enpoint Security ver 5. Seems like it blocked/hogged some files. My Error did not state which exe or file was in use so it took a long time to finally get to what JoeC said about Antivirus and tried it. Seems to be working now (Visual Studio 2010 SP1)
Closing recently changed User Controls solved the problem in my scenario. Hope this will help somebody out there.
Looks like this issue has (finally!) been fixed in the VS2010 SP1

Please try uninstalling Windows Live SYNC. Does it still happen?
I think I just found the culprit and the solution.
Go to services and stop & disable the "windows search" service.
That solved the problem for me now.
For me the solution was to change the startup project to a dll (problem only occurs in debug mode when having an application as the startup project). If your solution contains several projects (and it will, and it will contain a .dll, else you would not get the problem), switch to that .dll, no .vshost.exe, no problem.
Also, killing .vshost.exe did not work for me, since immediately after starting again, it had locked the .dll.
Also, make sure to have your references clean, especially in more complex projects, and also prefer project references to assembly references, and so on. I suppose bad references (circular and similar) are bound to cause problems, at least so I have read.
A short article by me on this problem (and my solution)
How to "clean up" your references in a solution
Adding the following to the Pre-build event of the shared dll worked for me:
if exist "$(TargetPath).locked*" del "$(TargetPath).locked*"
set exitprebuildfor$(ProjectName)=
for /l %%a in (1,1,10) do (
if defined exitprebuildfor$(ProjectName) goto :ok
if not exist "$(TargetPath).locked%%a" if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked%%a" & set exitprebuildfor$(ProjectName)=1)
:ok
set exitprebuildfor$(ProjectName)=
It's based on the solution given here but instead of just renaming the dll to .locked it keeps trying to rename it to .locked1, locked2. Using 10 I usually run into the problem once a day, but ant value can be used.
Simply make a copy of the whole project and run project from the new copy.... it will work fine.
But you will have to end process of the debug somehow in-order to delete the older project.
Stop IIS service and try building it again or if you can afford to restart your pc, give it a try. Worked for me both ways.
Cheers
My problem was that Outlook 2010 (outlook.exe) was using the same port as my ASP.NET MVC project with IIS express.
Solution: close outlook.exe, run your solution and open outlook again (so that it uses another port).
Hopefully this helps somebody, because I received the same error message as described in this topic.
Try deleting .exe file in debug or release folder (whatever you working on)
Windows will prompt that the process X has opened this and you can't delete it
after that go to task manager and in details tab end task X process
Delete obj file.And stop your service and Restart again.Then you may solve the problem
The best solution for me was to move my project files out of My Documents - which is on a server managed by the IT department - and locate them locally on my C drive. Also working: unchecking the "Enable the Visual Studio hosting process" checkbox, as stated by other people.
If you are working on a C# project which is using reference of C DLL, then you can eliminate the error by checking the Allow unsafe code check box. I know I have not used pointers in my C# project but I was using some bitwise operator in C#. May be these C-like features morphed it as 'Unsafe' code.
What worked for me was removing "read only" status on the bin folder. Once I did that, it has worked ever since.
I've had this error when the project is on a remote share (like, if your $env:homepath is helpfully redirected by your IT department to a network share). Make sure your project is resident on a local drive.
My problem started after creating a custom control and drag and drop it to the toolbox palette for use it in design forms. First appeared a warning saying that there was a redundance between the custom control source file (.cs) and the projects executable (.exe). On executing/debugging appeared the error: unable to access the (.exe) because it's being used (and it was true).
A literally removed the whole source code regarding the custom control and last problem never stopped, until I checked out the references and it was referencing itself in order to be "able to" get the former custom control. I removed the reference and done!!
So: just check the references and remove the self-reference to the project.
Delete your Bin folder and run the application.
This worked for me. :)
Simply turn off Visual Studio hosting in debug, run the project and again re on it and run project.
Open a project in Visual Studio.
. On the Project menu, click Properties.
. Click the Debug tab.
. Clear the Enable the Visual Studio hosting process check box
For Windows Project
The Visual Studio hosting process can hold the executable file pointer. To stop the host instance, open the Project properties and then go to Debug tab. Now uncheck the Enable the Visual Studio hosting Process option and then check the checkbox again to debug.
For web project
The IIS can hold the file pointer. Restarting the IIS can solve the issue.
I have a couple of VS 2008 projects (C++) that are linked every time I start a build, even though nothing has changed. i.e. I select "Build Solution", it compiles and links, I select "Build Solution" again, it doesn't compile anything, but links again.
This is quite annoying and I have checked everything that might cause it to link again.
Is there a way to find out why Visual Studio does or skips certain build steps?
Any input is appreciated!
I had some time to revisit the problem and a workmate gave me the tip to use "process monitor" from sysinternals to figure out which file is missing.
Lo and behold it worked! It turns out that Visual Studio insists on linking against a bunch of libs even if the app does not need it. Due to an unfortunate (I guess...) chain of events, one of the default library paths disappeared from Visual Studios global settings, so VS couldn't find this lib anymore ("coredll.lib" in my case).
This didn't affect the final output, because this lib is not needed at all, but it still triggered a relink every time.
There are two possible fixes:
1) Restore the path to this lib in the global Visual Studio settings
2) Use "$(NoInherit)" in AdditionalLibraries to get rid of the unneeded lib.
I used solution #1, because #2 needs to be done for each configuration of each project because can't be done via Property Sheets.
Rebuilding can be caused also by non-existing and unused .h files belonging to the project. Since they are unused, there's no warning nor error about missing files.
Using "Process Monitor" by Sysinternals as mentioned earlier was a great hint towards figuring out the reason.
Bit of a long shot but check the date/time stamp on any dependent DLLs you have. If they are in the future then a rebuild will occur.
Edit: Also have you tried opening the .vcproj files up in an editor to check if anything's unusual? You could also try recreating them from scratch, if that's possible.
Recently I started to get this message randomly:
Metadata file '...\Release\project.dll' could not be found in Visual Studio
I have a solution with several projects in it. The current build mode is Debug and all projects' configurations are set to Debug. But when I try to run the main project - sometimes it gives me a few errors, all of which are "Metadata file '...\Release\projectX.dll' could not be found" - and, look, it says about RELEASE folder, though current mode is Debug. Why? I tried to search for reference to "Release\projectX.dll" inside all solution files, and I found one in ResolveAssemblyReference.cache file.
I made a good search over the Internet and found a few people with a similar problem, but there was no solution, or at least no working solution.
I tried to delete references to those projects and read them, but in some time I start getting these errors again.
It seems like a bug. Why does it search for referenced projects in Release folders when I always use Debug mode?
PS. For those who met this problem: I couldn't solve it in an easy way. It disappeared only after I reinstalled Windows :(
Everyone is correct...try everything...(in order of a little to a lot of time wasted)
Do you have bad code? Fix that first.
Clean Solution & Restart Visual Studio
Remove / Add References
Check your build order w/ larger projects and verify
Manually rebuild sub-projects
Manually copy dlls between projects into associated bin folders
Go get some coffee, play some pinball and come back tomorrow...you may think of something else in the meanwhile.
I had the exact same problem. Big visual studio solution with 50+ projects.
All references were added as projects.
Project build order was correct (right click on project and select build order).
However when building some of the higher level projects the "root" project they depended on were not built.
The problem was that these projects were not selected to build under the current configuration (don't know how this happened).
To check this select "Configuration Manager" (Build menu) e check if the problematic projects are set to build.
When you say you deleted references to those projects and re-added them, how did you re-add them, exactly? Did you use the "Browse" tab in the "Add Reference" dialog in Visual Studio? Or, did you use the "Projects" tab (which lists neighboring projects in your solution)?
Edit: If you use the "Browse" tab, and manually add the reference to your .dll that is located in the /Release folder, then Visual Studio will always look for the .dll in that location, regardless of what mode you're currently in (Debug or Release).
If you removed the actual .dll file from the Release folder (either manually or by doing "Clean Solution"), then your reference will break because the .dll does not exist.
I'd suggest removing the reference to ProjectX.dll, and add it in again--but this time, use the "Projects" tab in the "Add Reference" dialog. When you add a reference this way, Visual Studio knows where to get the appropriate .dll. If you're in Debug mode, it will get it from the /Debug folder. If in Release mode, the /Release folder. Your build error should go away, and you also will no longer be (improperly) referencing a Release .dll while in Debug mode.
Well, my answer is not just the summary of all the solutions, but it offers more than that.
Section (1):
In general solutions:
I had 4 errors of this kind (‘metadata file could not be found’) along with 1 error saying 'Source File Could Not Be Opened (‘Unspecified error ‘)'.
I tried to get rid of ‘metadata file could not be found’ error. For that, I read many posts, blogs etc and found these solutions may be effective (summarizing them over here):
Restart VS and try building again.
Go to 'Solution Explorer'. Right click on Solution. Go to Properties. Go to 'Configuration Manager'. Check if the checkboxes under 'Build' are checked or not. If any or all of them are unchecked, then check them and try building again.
If the above solution(s) do not work, then follow sequence mentioned in step 2 above, and even if all the checkboxes are checked, uncheck them, check again and try to build again.
Build Order and Project Dependencies:
Go to 'Solution Explorer'. Right click on Solution. Go to 'Project Dependencies...'. You will see 2 tabs: 'Dependencies' and 'Build Order'. This build order is the one in which solution builds. Check the project dependencies and the build order to verify if some project (say 'project1') which is dependent on other (say 'project2') is trying to build before that one (project2). This might be the cause for the error.
Check the path of the missing .dll:
Check the path of the missing .dll. If the path contains space or any other invalid path character, remove it and try building again.
If this is the cause, then adjust the build order.
Section (2):
My particular case:
I tried all the steps above with various permutations and combinations with restarting VS few times. But, it did not help me.
So, I decided to get rid of other error I was coming across ('Source File Could Not Be Opened (‘Unspecified error ‘)').
I came across a blog:
http://www.anujvarma.com/tfs-errorsource-file-could-not-be-opened-unspecified-error/#comment-1539
I tried the steps mentioned in that blog and I got rid of the error 'Source File Could Not Be Opened (‘Unspecified error ‘)' and surprisingly I got rid of other errors (‘metadata file could not be found’) as well.
Section (3):
Moral of the story:
Try all solutions as mentioned in section (1) above (and any other solutions) for getting rid of the error. If nothing works out, as per the blog mentioned in section (2) above, delete the entries of all source files which are no longer present in the source control and the file system from your .csproj file.
I've had this problem before and the only way I've found to solve it is to run Clean Solution and then restart Visual Studio.
For me it's usually the target framework being off (4.5.2 instead of 4.6) If you fix the target framework of the project to match the target framework of the solution and build, a new .dll will be created.
Re-open Visual Studio as Administrator.
Most of the answares say that you need to remove the libraries of your solution, this is true but when you re-add the libraries the error will be shown again. You need to verify if all the libraries referenced have a compatible .net framework with the .net framework of your solution. Then fix all the errors in your code and rebuild the solution.
Did you check the Configuration manager settings? In the project settings dialog top right corner.
Sometimes it happens that between all the release entries a debug entry comes in.
If so, the auto dependency created by the dependency graph of the solution gets all confused.
I've also seen this error in solutions where I have multiple projects (usually netTiers projects where I've updated one or more of the sub-projects to target the 4.0 framework). It can be problematic to remove. Oftentimes it can be resolved, however, by first fixing all other errors in sub-projects (eg, any missing references), individually rebuilding those sub-projects, then removing/adding back any references to those sub-projects in Visual Studio. Personally, I've had little luck resolving this error by cleaning the solution alone.
We recently ran into this issue after upgrading to Office 2010 from Office 2007 - we had to manually change references in our project to version 14 of the Office Interops we use in some projects.
Hope that helps - took us a few days to figure it out.
In my case it was caused by two things (VS.2012):
1) One of the projects was configured for AnyCPU instead of x86
2) A project that was referenced had somehow the "Build" checkbox unchecked.
Do check your Build | Configuration Manager to get an overview of what is being built and for which platform. Also make sure you check it for both Debug & Release as they may have different settings.
In my case, I had some errors in my code. Visual Studio showed the error you had instead of the actual errors, like syntax errors or unknown class names. Try cleaning the solution and building project after project. This way you will discover the actual errors.
Again, this is just what cause the error for me.
I had this problem and took long while to figure it out. Problem came up when I removed projects from solution and replaced those with nuget packages.
Solution seemed to be fine but the .csproj file still contained those projects multiple times as reference.
Seems that VS does not clean that file appropriately. It was still referencing the removed projects under the hood. When manually removed the references from csproj file all works again! wohoo
This problem is due to pdb files or CodeContracts.
To resolve it:
Clean your output folder and rebuild the solution.
Re-Configure the CodeContracts or disable it for temporary build.
We have that problem quite often, but only with references to C++/CLI projects from C# projects. It's obviously a bug deep down in Visual Studio that Microsoft decided not to fix, because it's 'too complex' and they promised an overhaul of the C++ build system which is now targeted for Visual Studio 2010.
That was some time ago, and maybe the fix even went into Visual Studio 2008; I didn't follow up on it any more. However, our typical workaround was
Switch configuration
Restart Visual Studio
Build the solution
I had the same problem myself.
Visual Studio 2013 only told me that it couldn't reference to it, and it couldn't find the metadata. When I opened my solution (which has multiple projects in it) it said that I was using projects lower than the framework version of one of my projects.
So I switched everything to version 4.5, and it worked again.
I seem to recall having a similar problem a few months ago. I solved it temporarily by copying the referenced DLL to the Release folder, thus satisfying Visual Studio's expectations. Later, I discovered the reference to the Release DLL in my actual code. You should try doing a search through the entire project for \release\project.dll.
Also, I have noticed that Visual Studio unit test projects sometimes put a "DeploymentItem" attribute on each of the test methods pointing to your target DLL, and if you switch between Debug and Release, Visual Studio can get confused if the DLL is no longer in the expected location. In my experience, these attributes can be safely deleted if you didn't put them there yourself as part of a "single deployment" scenario.
I had this problem and it was due to an invalid method in the offending library (dll) that did not return a value, e.g.
public bool DoSomething()
{
//I never bothered putting code here....
}
When I commmented this out everything compiled :)
Sometimes VS2010 switches my configuration from Any CPU to Mixed Platforms. When this happens I get this error message.
To resolve it I switch back to Any CPU:
1. Right click on the solution and select properties.
2. Click on Configuration Properties and then the Configuration Manager... button.
3. Under Active solution platform select Any CPU
I find that this usually occurs to me when i still have a method declaration in an interface, which a class implements, but that i had later removed and had forgotten to remove it from the interface as well. I usually just save the entire solution every 30mins n then just revert back to an earlier version if i cant find the error.
I ended up deleting my references (I had added them properly using the projects tab, and they used to build just fine), hand editing my .csproj files and removing bizarre entries that didn't belong -- and setting my outputs for debug and release, x86 and x64 and any cpu to all be "\bin" -- I built it once, then re-added the reference (again, using the projects tab), and everything started working again for me. Didn't have to restart Visual Studio at all.
For me this was caused by the Build target having been rewritten to not output the dll. Removing this to fall back on the default Build target fixed the issue.
For me was to remove/delete entire .vs folder(that is an invisible one) and then:
- Build
- Rebuild
and done.
in my case i was working on a branch off master. so i checked out master branch, ran a build and then checked out my branch. It fixed the issue. If you already are on master, i suggest you check out previous commit and then build it.
It seems to happen when you checkout a solution with multiple projects that have references between them, and you haven't built it before. If you have references directly to the dlls, instead of referencing the project, you'll get this message.
You should always use the Projects tab in the Add Reference dialog to add a reference to a project in the same solution. This way, VS can know the correct order in which to build the solution
same happened to me today as described by Vidar.
I have a Build error in a Helper Library (which is referenced by other projects) and instead of telling me that there's an error in Helper Library, the compiler comes up with list of MetaFile-not-found type errors. After correcting the Build error in Helper Library, the MetaFile errors gone.
Is there any setting in VS to improve this?
I had the same problem. I noticed that my db context (EF4) that was located in the project dll wasn't recognize for some reason. I deleted it and created another one instead. and that solved it for me.
Had the same problem today.
My application, a Windows Forms applications, accidently had a reference to itself. Weird.
Once removed, the error went away.
The reference got added each time I dragged a user control, located in the Windows Forms project itself, to a form.
I had the same problem. Manually removing and adding the dlls did not help. ClassLibraries did not compile for all the projects and were missing in the ...\bin\Debug folder for the project [because I cleaned solution by mistake]. Since the class library did not compile that means there may be some errors somewhere in one of those sub projects.
Solution: Since my dlls were there for the ...\bin\Release folder, I tried to rebuild on Release mode and found an error on one line in one of the sub projects. Solving the error and rebuilding the solution got rid off the build error.
I have a solution with several projects, where the startup project has a post-build event that does all the copying of "plugin" projects and other organizing tasks. After upgrading the solution from VS 2005 to VS 2008, it appears as though the post-build event only fires if I modify the startup project, which means my updated plugins don't get plugged in to the current debugging session. This makes sense, but it seems like a change in behavior. Is anyone else noticing a change in behavior with regard to which projects get built?
Does anyone know of a workaround that I can use to force the startup project to rebuild whenever I hit F5? Perhaps I configured VS 2005 to work this way so long ago that I've forgotten all about it ...
I think you need to reorganize the responsibilities. Each component should be responsible for itself and therefore copy its generated goodness where it needs to go. That way it doesn't matter if/who/what/when/where got built. Whatever is updated will put itself into the proper place.
IMO the other suggestions are no-nos since they'll circumvent the compiler's smarts to know when a rebuild is necessary for the main project. And hence killing any compile time-savings. If your "plugin" projects are assemblies (and not just project-references from the main project), then you do not need to rebuild the main project each time a plugin is rebuilt. The new assembly will get selected into the process / debugger w/o the main project needing a rebuild.
Why not just add a dependency to the "startup" project for each of the plugins? This will force the project to be rebuilt if any of the others change, and you won't have to mess with any other pre/post-build events.
I don't know if this is the right way to do it but you could add a prebuild event to your startup projcet (if it's static) to clean the project which will force a rebuild.
something like:
devenv project.csproj /clean
This is a pain. What we really need is for Microsoft to allow us to hook into a Post-Solution Build event. You can do this via macros but that's too complicated.
I'm assuming this is a C++ project because I don't have this problem with C#.
This is my solution, it's not elegant but it works:
Create a new project whose only purpose is to run the post-build script. Mark it as dependent on every other project in the solution.
Add a dummy file to that project called dummy.h or whatever.
Right click on dummy.h in Solution Explorer and select Properties.
Select 'Custom Build Step'.
For the command line type 'echo' and for Outputs just type 'dummy' or something else that will never exist.
This project, and therefore the post-build script, will now be run on every build.
John.
flipdoubt: they are projects created originally in 2008. My suggestion if it's not working C# is to look in the Build Events tab and check the setting of the "Run the post-build event:" drop down. If it is set to 'When the build updates the project output' this might be your problem, try setting to 'On successful build'.
John.
I'm having the same issue here and it is VERY annoying. John Richardson is right in that there should be a Post-Solution Build event (and a Pre-Solution Build event) that applies whenever ANY project in the solution is being built.
I don't think there is any good workaround to get this outcome in the current VS 2008 IDE.
Starting from #lomaxx suggestion, I got a very similar setup working by adding the following line at the end of the post-build event of the startup project:
"$(DevEnvDir)devenv.exe" "$(ProjectPath)" /clean
Note that this makes the startup project build the next time you need to debug, so you should make sure the project gets built at least once.
PS. I initially tried the pre-build as suggested, but that didn't work (and I think it makes sense - if VS thinks a project doesn't need building, it won't execute any events for that project).
