I downloaded an ASP.NET open source solution and opened it in Visual Studio 2010. VS is running as admin.
Everytime I switch the solution or a project from Active (Release) to Debug and uncheck 'Optimize code' and save, these changes don't stick. The solution or project reverts back to Active (Release).
Why is this happening?
You also have to change it in Configuration-Manager (see pictures).
I just had this exact issue. The solution ended up being:
Go to Tools ⇒ Options ⇒ Make sure "Show All Settings" in the lower left is checked.
Then, in that same window, go to Projects and Solutions ⇒ General ⇒ check "Show advanced build configurations".
I have no idea why this checkbox was suddenly unchecked for me this morning, but this worked.
This is guessing a little, but anyways:
Most likely, you are using build configurations that don't include your start up project for Debug build.
Look for the 'Manage Build Configurations' (I think, no Windows machine nearby) menu item. It will show you a list of projects with tickboxes on the right to show whether it is to be built in the build configuration.
Switch to 'Debug' in that dialog and make sure your startup project - or the project that your starting the build for - is actually included in the build.
PS It is even entirely possible that the 'misbehaving' project is actually lacking a Debug build (it might have a deviant name, like DebugConsole or something else entirely). In that case, use the Project menu to add a build configuration of the proper name for that single project. Afterwards, check (again) that said build configurations are checked in the 'solution wide' build configuration dialog.
HTH
Changing the properties of a configuration doesn't change the current build configuration. If you open project properties, change from Release to Debug and make some changes, after exiting the dialog, you will build on the same platform as before. To change the platform you're building on, there is a combo-box right above the code - use that. You should have all available configurations in the list. When you open the project preferences dialog, the current configuration will be the default one in the dialog.
I opened the csproj file in a text editor. Noticed there were two PropertyGroup sections which look like duplicates, one was Debug|AnyCPU and the second was Release|AnyCPU. I deleted the second one and the debug one showed up.
Luchian Grigore's answer explains correctly one simple misconception that could lead to this problem and aaaaaaa's answer gives another way of correcting it: there is a dialog that looks like you are selecting the configuration to build but you are actually just selecting the configuration to configure.
However neither of their ways of opening the 'Configuration Manager' actually worked for me -- I had to click on the button configuration manager at the top right of the solution Properties.
(Note that the place where you choose the configuration is called Configuration Manager, whereas the place where you manage the configurations is Properties.)
.NET 4, console application. The project is set to 'Debug' mode. The breakpoint being set is in the primary/startup project. I have right-clicked -> Clean, and right-clicked -> rebuild, both on the Solution and project levels.
Following the instructions in this SO question, I have confirmed that my "Build and Run" options are set to 'prompt' for both 'When projects are out of date' and 'when build or deployment errors occur', and I am NOT getting a prompt when I F5 to build/run.
Also, the 'save all changes' under 'before building' is also selected (plus I manually saved them myself).
I monitored the output window of the application, see this line:
'MyApplication.exe': (Managed (v4.0.30319)): Loaded 'C:\exepath' Symbols Loaded.
I restarted the VS2010 instance. I restarted all open VS2010 instances (of other projects). I've even gone through a reboot.
However, the breakpoint I am setting in the startup project is a hollow-red circle, with the notice that 'This breakpoint will not currently be hit, The source code is different from the original', and, in fact, is never hit.
So, this is really 2 questions:
1) How do I fix this problem so I can properly breakpoint
2) When I see this, does that mean my code is executing from an older build?
I've had this problem once myself but that was on a vsto addin. In that case there were left over intermediate files under the users/appdata directories that were actually loaded instead of my app.
There is this blog article that has a whole load of possible reasons for this error and then a whole bunch more in the comments from other users
This can also happen if you have a solution with multiple projects, and have the wrong project selected as your startup project in VS2010 and VS2012.
Now, obviously, I wouldn't expect debugging to work if I have the wrong startup project selected -- the debugger is attaching itself to the wrong process!
But this error message (in my case) was terribly misleading. It made me think something else was wrong. I tried a bunch of solutions in this thread (nuking various /bin and output directories) when really it was something very simple (wrong startup process).
If you are using vb, check that you are building the project for the active solution configuration (Build, Configuration Manager..., Column under Build is checked. Also check the project properties, Compile tab, Advanced Compile Options, and Generate debug info is set to Full. Sorry I can't tell you where this may be in C#.
The only other time I've seen this is when two projects in the solution are referencing the same dll but they are referencing from different sources. One from a project reference and another from a file reference for example. If the "copy local" option is true, there would be the potential of overwriting the dll with an older version of the same dll.
My solution might help people who have signed the assembly.
After lot of head scratching for the past two days, I was able to resolve the same issue by doing the following simple steps:
Go to your Visual Studio project properties.
Go to the "Signing" tab.
Uncheck "Delay sign only" option if it is checked.
Now run your project and it should work.For me it did work.
In my case was this same problem (“The breakpoint will not currently be hit. The source code is different from the original version.”) caused by fact, that I tried add breakpoint to declaration:
DateTime dt;
bool b = DateTime.TryParse(null, out dt);
(first line of code)
So I assume that message is "universal" and may have many different causes.
This can happen if your system clock was changed since the last compile. Your PDB file will be different date than the one your are trying to debug. Delete the PDB files in the project and recompile.
I experienced the problem when Project > Properties > Web did not have "Enable Edit and Continue" selected. After enabling this feature the issue was corrected.
It is important to note that under Tools > Options > Debugging > Edit and Continue "Enable Edit and Continue" was selected, but it was not enabled for this project.
Just go to Tools / Import and Export Settings
Choose reset all settings then click Next
No, just resetl settings, ovewriting my current settings then click next
Choose your current language, por example C#. then click Finish
If you have multiple solutions open, try simply closing all Visual Studio instances and restarting only the instance you need.
In my experience this has happened when two branches of nearly identical code are open in different instances.
doing a "clean solution" from VS Build Menu might help you.
I had to go over all those steps to fix the issue on my computer.
Make sure that debug = "true" on your web.config
Clean and rebuild all projects
Delete every file inside the bin folder of all projects
Close and open Visual Studio, rebuild, and run the project again.
Go to your solution folder -> obj -> Debug - > delete the .dll file and build the solution again.
I'm working on an IronPython project on VS2010 and I've notice that for the python project (which is setup as a Console project, but really just contains a number of scripts that are hosted in a C# app), everything that is in the project directory will show up in the VS solution explorer under that project. So, for example, the .svn folder shows up. Which I obviously don't want or need to be there.
Is there any way to tell it to hide specific items? I sure can't find one.
Currently we have a directory based project system - which as you have seen includes all of the files in the project dir. We were planning on having an exclude option but the feedback we've been hearing so far is that we should move to a normal VS project model where you need to explicitly add the files. The next CTP release (which should be out in a week or so) will change to a normal project model.
There does still seem to be some interest in the directory based model so we may bring it back via an option in a future version.
You should be able to just right click the folder, choose "Exclude from Project"
Then, make sure "Show all files" is NOT on at the top, by the solution.
I cannot get rid of this in my VS 2008 web project when debugging. I've checked that it's in debug mode on the non-web project in question and it's in Active(Debug). Deleted all items in my .NET 2.0 temp folder in Windows. Not sure what else to do here.
Try disabling "Enable Just My Code" in Tools/Options/Debugging/Options.
I had the same problem and discovered that I wasn't outputting my debug info on my build. If you right click on the project and go to 'properties', then select the 'build' tab, on the bottom of the page there's an 'Advanced...' button that will display your setting for you output debug info. Set that to 'full' and the error should go away.
I just ran into this issue, and quickly decided that the other answers posted didn't apply to me.
I'm the owner of the project, and I know it was built with debug information, as well as without optimizations. Furthermore, I'm never happy choosing the disabling of a warning as my first choice. Hiding/ignoring this warning could become an issue in a future debugging session.
Since this only started occurring after I signed the assembly, this clued me in on my quick fix: temporarily remove the strong name of my DLL (and consuming EXE). Voila! Problem solved.
A better, long-term solution, could take the form of adding a post-build action to update the GAC so it has the latest version of the signed DLL.
But for now, I'm happy to move on from this diversion, and continue working on the issue that brought me to this debugging session.
resolved. Deleted all occurences (all projects) of the dll in question.
VS2012, clean and rebuild fixed the issue for me. "Properties" -> "Build" -> Optimize code is unchecked. "Properties" -> "Build" -> "Advanced" -> Debug Info: Full

try unchecking "Just My Code" in Tools->Options->Debugging->General.
it works for me
Guessing VS 2008 is not rebuilding the dll correctly.
1) Delete all occurrences of the dll
2) Rebuild solution
And that should fix it.
Check your build configuration options. Make sure optimizations are turned off and the DEBUG constant is defined.
If everything else fails, try renaming the Assembly name in the project's properties. This fixed the issue for me.
I get this issue as well, for some reason it's happened 3 or 4 times; I think it must be a Visual Studio 2005 bug/hick up (or at least my installation).
This has worked every time: to fix it I
Right click on my solution and click Properties.
Open Configuration Manager.
Select Debug in the drop down menu (if not already selected).
Uncheck BUILD. Then re-check it.
Rebuild the solution.
Tools > options > Debugging > Symbols > Specify excluded modules
look that if the dll or the exe in the excluded modules list
At least for non-web applications this works:

2 - Allow Debugging...
Due to the nature in which one of the assemblies has been built in your application, you will need to change a few settings to allow the code to be handled by the Visual Studio Debugger.
Right click on any project in question from the solution explorer and select 'Properties'. This will open up the project properties panel giving us access to a great many options for our projects. Navigate to the 'Complile' Tab (or 'Build' if your in a C# environment) and select 'Advanced Compile Options...' from the bottom of the screen. This presents us with a prompt that has two key areas of interest:
1) Optimizations - uncheck 'Enable Optimizations'
2) Generate debug info - Ensure that the option is set to 'Full'
I had this issue with a solution in a certain folder, but if I moved it to another folder or others built it, I didn't get the message. I did the clean, rebuild, and even rebooted and still couldn't get the original to debug without this message. I searched my system for copies of the file causing the error and I found that copies were kept in
c:\User\username\AppData\Local\Assembly\dl3
This was on Win7-64 but will be similar on other Windows OSes. I deleted all of the copies I found there and I no longer get the message. I didn't need to uncheck the "Enable Just My Code".
Also, this was for a WPF app, but I came across this thread in my search so hopefully this will help someone else.
I was able to resolve this issue by following these steps:
Right-click on the Solution (not the Project), and select 'Properties'
In the left panel, select 'Configuration Properties'
In the right panel, select 'Debug' under the 'Configuration' column for your project
If you do not see the Solution listed in Solution Explorer, follow these steps:
In the menu bar, go to Tools -> Options
In the left panel, select 'Projects and Solutions' (you may need to check 'Show all settings' at the bottom-left area of the window
In the right panel, check 'Always show solution'
I hope this helps.
I too have all these. And I've done all this. It appears this happens to me every time I get a fresh copy of the entire solution out of source control. So if we've done all these, deleted dlls & .pdb files for all references (Assemblies) in the web project, used the clean option on the solution, deleted temp files, closed out VS and reopened, made sure debug mode is selected and set at full and optimations are off, what more is there?!?!?!
I had the same issue on my web project in Visual Studio 2010, and finally I found the reason why I was getting this message. What I did was to change an existing debugging option on Visual studio:
Go to Tools->Options->Debugging->Symbols->All modules
Check the "unless excluded" radio button
Click on the link "Specify excluded modules", then remove the DLL that you want to debug.
In my case it was my web dll file...
I had this when trying to remote debug an application on a computer that belongs to a different subnet. I was able to debug and step through the code when running it across the network if the machines were on the same subnet. After changing the subnet though I was unable to step through when running from the network and was getting the "The Following Module was built either with optimizations enabled or without debug information".
The solution? Easy. Copy the built solution across to the machine hosting the remote debugging and run it locally.
Had this happen to me on a VS 2010 winForms project. Seeing that the majority of people here have web projects, i think that it has to do with access to the folder in which the project is stored. I say this because when this problem occurred to me Google Drive was synchronizing the folder in which i keep my projects. It seems that just disabling the synchronization does not fix the problem.
My solution is similar to one of the answers above:
Went to "Project Properties > Compile > Advanced Compile Options"
Checked "Enable optimization"
Set "General debug info:" to "None"
Unchecked "Define DEBUG constant"
And pressed OK
Then went back and returned the options to their initial state.
Hope this helps someone as it seems this still happens.
Follow this : (first STOP debuging)
1:right click on project solution name or project -> Properties
2:under Configuration Properties select configuration Manager
3:Change configuration to debug and click on close
4:Change configuration to debug and click on Apply -> OK
Now rebuild solution....!
For me, Checking the "Optimize code" box in the project properties, saving, unchecking it, then resaving did it for me.
Disabling "Enable Just My Code" also worked, but that was more of a work-around than a fix as I didn't want that setting.
I have had same problem, but with different cause and solution.
The window was the same as that shown by Gustavo (above) but the path was in:
"\users\zzz\AppSettings..." (where zzz is windows username)
I had an Excel addin - I was testing the install of the addin, so I had a copy installed through VS install function. VS was obviously trying to debug both the installed copy and the copy I had just launched, and could not find debug symbols on the installed copy.
None of the above solutions worked (without side affects),
SOLUTION:
uninstalling the addin, and manually deleting the files in App Settings worked.
You mentioned it's a web project...do you have
<compilation debug="true />
in your web.config?
I had the same problem after building with a Release configuration.
It turned out that when I switched back to Debug, VS wasn't detecting any differences, so it was not updating the .dll and .pdb files in the bin folder.
Here's what worked for me:
Run iisreset (to clean up the temporary folders)
Save the web.config (to force VS to actually rebuild)
Rebuild on Debug
Start the project
Try a rebuild then debug.
My case is following: webservice referenced lib1.dll. Later I removed reference as it was no longer used. However lib1.dll remained in the bin folder.
Because library was not referenced then Rebuild and Clean actions were not helpful.
After manually deleting lib1.dll from bin folder I've get rid of this message.
If you are publishing to IIS and not using built in web server -or IIS express- make sure that your publish profile settings is in debug mode. In vs 11 by default it's in release mode.
Just to add, I was looking at this blog to find the solution to the same problem I was facing. Unfortunately the solutions mentioned above didn't help me. At last I figured out, I was installing my bits (along with .pdb) through installer and setting permission explicitly on the installation folder.
Because of which VS was not able to load the pdb even though the file browser was showing the correct file but it was giving the same error mentioned above.
Once I unchecked "Enable Just my code" and removed permission settings from the installer, VS started loading the module.
The one configuration that worked for me was the following
Project --> (Your Project) Properties --> Debug Tab
make sure Configuration is set to Active (Debug)
Under "Unable Debuggers", make sure "Enable unmanaged code debugging" is checked
I'm creating a Windows Service and here's what worked for me:
Uninstall the service.
Open a command prompt and go to c:\Windows\Microsoft.NET\Framework64\v4.0.30319
installutil C:\MyFantabulusWindowService\bin\Debug\MyFantabulusWindowService.exe
Greatness has been achieved!
Case : testing assembly with Console project in SharePoint development - if you're doing SharePoint development and seeing this alert in VS, make sure you deploy your SP assembly to the GAC before testing your console app IF your core SP project has methods you need to call in your console test app.
Can you set the startup Project in the Visual Basic 6 IDE?
I looked all through the Settings and can't find a way to do it.
I assume you have multiple projects in a Group e.g. a dll and a dependent exe and you want to set the exe as the 'start up' project. Do so this, select the exe project in the Project Explorer, right click and choose 'Set as Start Up' from the context menu. The 'start up' project's name will be shown as bold text in the Project Explorer.
Dave and OneDayWhen are correct in saying that you need to right click the desired project in the IDE and select Set as Start Up when you have multiple projects loaded and you want to choose which one is executed.
Anyone know how I can set the VB6 IDE
to load either the last project loaded
or change the default one loaded?
Copy the Icon change the target to something like
"C:\Program Files\Microsoft Visual Studio\VB98\VB6.EXE" "D:\MyProjects\MyOneProject\trunk\MyOneProject.vbp"
Change Startup In to D:\MyProjects\MyOneProject\trunk
I found it more just to change the StartupIn to my Master Project Directory rather than have icons for specific project. Like D:\MyProjects

P.S. In case you are wondering on why you would ever select a non-EXE project as startup. You do this at times when you are debugging a non-EXE. When you startup a non-EXE you have several options. Among them you can fire up a application,or have sit there until something calls it. Useful when you are debugging a Active DLL or Control and using Excel or another 3rd party software that you don't have the source too.
I'm not aware of a "startup Project" settting in VB6, but you can select the "Startup Object" by opening the Project menu, choosing the last menu item ("X properties", where X is the name of your project), and then selecting the General tab in the Project Properties window. The selector you seek is in the upper-right corner.
