Out of nowhere the "Publish Web Site" option in Visual Studio isn't doing anything for a particular project. It still compiles the site (no errors), but it never copies the output to the destination directory. I've tried changing the destination to a number of locations, and it creates the new folder, but never copies the output. I tried other projects and they seem to work fine. What would stop one project from copying the output?
Update: This is a web site project, if that makes any difference.
It appears the problem was with the "Allow this precompiled site to be updateable" option. This was turned off at some point and was causing the problem. Turning it back on caused the files to be copied again. Why should this make a difference? Is there another setting somewhere that needs to work in conjunction with this setting?

I am developing a VB.NET (4.5 framework) solution in Visual Studio 2015, Win10 OS, and have been able to run the builds uninhibited for several months, but now I am receiving the following error upon starting the build:
vbc : error BC2012: can't open
'C:\MyProject\ProjR5\ProjR5\obj\Debug\ProjR5.exe' for writing: Access
to the path 'C:\MyProj\ProjR5\ProjR5\obj\Debug\GenTagR5.exe' is
denied.
At first, VS2015 would give me the option to run the last successful build, but even that is no longer an option. After exhaustive internet searches on this problem, none of the dozen or so given solutions are solving my issue.
Here is what I have tried in order to resolve the error so far:
Ran sfc /scannow (elevated prompt)
Using ProcessExplorer, find handle or DLL substring that included my project
Made sure there were no hanging procs (including procs with my project name, devenv.exe, [project].exe, [myproject].vhost.exe, etc.)
Restarted VS2015
Restarted VS2015, running "as Administrator"
Restarted Computer
Full Shutdown of computer
Complete Rebuild of Solution
Build->Clean Solution
Build->Clean Solution, then Build->Build Solution
Build->Rebuild Solution
Uninstalled and Reinstalled VS2015
Disabled all indexing
Removed "Read Only" attribute from entire project folder and files within
Checked startup scripts for like- or identical processes
Disabled all AV apps
Disabled all antispyware apps
Disabled all firewalls
Verified that Application Experience (services.msc) wasn't disabled (I'm using
Win10 ... it isn't even in the list of services)
Set Tools->Options->Projects and Solutions->Build and Run->Max. parallel
builds to 1
Rerun aspnet_regiis.exe (under .NET\Framework)
Checked Local Security Policies and verified account was listed under
"Impersonate a client after authentication"
Removed \bin and \obj folders
Put \bin and \obj back when removing them didn't help
Removed \bin and \obj folders, then Rebuilt
None of these have worked. Any suggestions?
The problem ended up being Samsung Magician's Rapid Mode losing data during its write-caching phase to my solid state drive. I turned off Rapid Mode, and now the project builds without any problems.
Sorry for came too late, but i had this problem and i wanted to show how i fixed for the next devs who need a solution:
It's quite simple, just change your proyect assembly name:1) On your solution explorer: Right click on your proyect.
2) Properties>> aplication>> assembly name>> change it.
3) Compile, run to test it.
4) Change the name again if u wanted the original name.
Adding a description:
Changin the assembly name
New 2 programing in VS but i had same problem of Access or Write exe file ON BUILD.
Problem came out of nowhere. I didn't use or make changes 2 exe file in months,
made exe file, used it now and then and forgot about it....
Then after few months i wanted 2 start exe but no icon on desktop ??? ....tried everything, lost 3 days of searching inside code for error in VS and then called Google....
I read last comment ABOVE which mentioned Bitdefender, opened it and found BitD did block and isolate exe files ..... so i tried exluding files and folders which made problems inside BitD but no help....
So i went back 2 VS.
Within debug i got some X86 processor error which didnt make problem to build but it was warning (free component name in error description helped me ), - errors you can ignore but they are here on build ....
So i made last move before starting it all over again. Removed COMPONENT from application, deleted it on PC ...started VS from start .. and ALL was OK !!!
So in my case it was all about FREE component i used in app inside VS .... Bitdefender found some add / virus in it and blocked build progress.
BitD deleted or blocked exe file in start....
Hope this help anyone with similar problem !
The cause of this error for me was that Team Foundation Server had pulled in a bunch of files to my work space as Read-only. Not sure why it pulled them down from the server with read-only checked, but all I had to do was uncheck it.
Ok. Create a new solution and add its directories to the exception list and copy all your work, except for the '.vbproj' and except for the '.csproj' and the directory files to the directory of the directory of the new solution. I have tried that and it works, due that I have Bitdefender, it will be the only way to sort that issue. After doing so, try to build the app again. If it does not work, then I am definitely out of ideas.
I am creating my own site template for SharePoint. Everything has been going fine, building fine, deploying fine. For unrelated reasons, I needed to reboot my development server. I then made an update to my custom.xsl file and attempted to deploy in Visual Studio 2012. Even though it says Deployed Successfully, My changes are not reflected in SharePoint, and I received the error in my question. Additionally, I am getting 32 warnings that this or that attribute is not declared, even though I made one small change (added a link for testing) to the blog.xsl I copied my custom .xsl from. I reverted all changes, attempted to deploy again, but cannot get past this error now.
Any ideas where to start looking to solve this? Needless to say _layouts is NOT in the root of the C drive, but it the 14 hive under Templates.
I've added a couple of lines to a file, let's say it builds to be foo.dll. It's part of more then one dll file, but it's the core dll. What I did was that I added a couple of lines so it should add some log data to the database. It should not affect any other files what so ever.
So i tried to deploy it. We don't have the magical one click deploy, we are just copying the right files to the right place.
So now, since i have a change in foo.dll, i thought for myself that i just could copy foo.dll and the server would be happy.
I was wrong. Browsing the website i now get "Generic Errors", dont know what that is. I've also tried to copy all the new dll files (4 i total) but that did not solve the problem either.
The error it gives are
Http Error 404.0 not found
Module: ISS Web Core
Notification: MapRequestHandler
Handler: Static File
Error Code: 0x80070002
replacing the new foo.dll with the old one solves the problem. and i've tried to restart the webserver. :-(
I asume you have "published" and not just "compiled" your Web?
You also need to take care off the "Solution Configurations": Debug and Release.
In a normal publish process you would change the configuration to release and publish your project into another folder.
After you have done that you just need to collect the desired files and upload them.
Keep in mind that you need the newest version of you web project. Maybe there are some changes online that your local project hasn'T. This would cause such problems.
We don't have the magical one click deploy
Why not? It's not magic, and it's pretty easy to set up. Get any continuous integration software (I would recommend BuildMaster since I am a developer for it and it's free now) and you'll never have this problem again.
I have a simple Silverlight program that displays a bunch of images. I modified it do display more images, but it when I hit "run without debugging" is keeps running the old build with fewer images. When I copy the code into a new project and run it, it works fine for the first time, but then each subsequent change is not displayed. What could be the problem? I'm using Visual Web Developer 2008 Express.
Always check "Configuration Manager" option on "Build" menu in Microsoft Visual Web Developer. The checkBox "build" has to be checked, otherwise it won't build.
Happened to me, I hope this helps others.
I just had this happen to me in VS 2013 for Web. Had to change the Project URL in:
"Project properties"
"Web" tab
"Servers"
To a different localhost number and recreate Virtual directory.
Before my Project URL was:
http://localhost:55487/
I changed it to:
http://localhost:55488/
Then clicked "Create Virtual Directory".
Would like to know why this happened in the first place.
I found that I had to close all open instances of Visual Studio before I got it working again
This happens because your cache memory is full. just go to you bin and obj folder and delete all the temporary files. Now it will run properly.
Maybe it's a caching issue (webbrowser / proxy).
To fool the browser try to embed the xap file with an additional parameter that changes every time you open the plugin:
<param name="source" value="ClientBin/BubuApp.xap?<%=Guid.NewGuid().ToString() %>"/>
If this don't help, try to clean the project (delete obj / bin folders & xap file).
I was also suffering from this issue and none of the suggestions worked. I was building a Office.js add-in and debugging was with IIS Express.
What fixed the issue for me was deleting files in
C:\Users\<user>\AppData\Local\Temp\Temporary ASP.NET
Actually, I went ahead and and deleted the entire C:\Users\<user>\AppData\Local\Temp folder out of spite :)
I also had this issue and while some of the fixes above helped temporarily, the one that worked for me was to remove the history and caching in Internet Options.
Go into Internet Option (also available in VS via Tools > options > Environment > Web Browser > Internet Explorer Options).
On the General tab click Settings in the Browsing History section.
On the Temporary Internet Files page select Every time I start
Internet Explorer
On the History tab set the Days to keep history to 0
On the Caches and Database tab make sure Allow website caches and
databases is NOT ticked.
I'm not sure if all of the above are required, but I've made a number of changes to files and so far they have been reflected straight away in the dynamic versions without any noticeable performance problems.
I've also since realised if I set 'Every time I visit the webpage' instead of 'Every time I start Internet Explorer' I don't have to stop and restart the project to see the changes. Which is how it should be!
I used to suffer this. All of this used to be (for me) a folder's contents issue.
Maybe you can check this:
Delete %windir%\microsoft.net\framework\v4.0xxx\Temporary
IIS Express: even if you change the output file for compiled results, you will see in applicationhost.config that many times IISExpress is really "looking" to the default bin folder of your project.
It is even possible that you have different configurations for Debug or Release, so maybe IIS is looking BIN with Release code, and you are now compiling in Debug to another folder, do you understand me?
Happened to me too. Well i dont know the exact reason for this behavior. But when i close the visual C express 10 and then open again and build it builds the new saved file. I guess it still hangs on to the old file when there is an error in some debug mode or something.
Stop all incntance of VS.
Delete all /bin, not just /bin/Debug. All /bin
Remove user option .suo file in solution dir. It will create on self.
Remove all restore windows point
Stop IIS.
6 Start IIS after 1 minutes.
Rebuild solution, Buid projects
It happing on me too. Very nasty. You may restart your computer.
Check for global asembly dll.
Just delete folder 'Release' in project with old code build.
I had the same problem and none of the answers were working for me. It turns out that building the ASP.Net project did not build the Silverlight project, so running without debugging didn't update the Silverlight.
Fix: Right click the Asp.Net project. Build Dependencies > Project Dependencies. Check the Silverlight project. Now building should work.
If this is a web application, change the Project URL with a new port number.
Example :
Change from http://localhost:3688/
To http://localhost:36881/
To do this:
Navigate to Project properties -> Web
Change the URL
Hit "Create Virtual Directory"
Finally, Build and RUN
I had this issue in a web site.
The site referenced 1 of the projects in the solution, and changes to it would not reflect in the debug.
Issue was a third project was referencing an outdated dll of the same same referenced project.
I removed the project and all references in other projects and readded and re-referenced everything and it worked fine.
Check you haven't got two versions of whichever file you're updating (one for one group of users, one for a different group of users).
In my case(VS 2015) it was because of the missing dll in the .exe directory... I made a "clean solution", then additionally deleted all bin and obj folders' contents. Reason to do so was VS keeping to load old dll build. Solution was to select folder of the running debug config, i.e. everytime I rebuild project destination location with dll and a reference to it stays with warning mark for some time until intellitrace does its job. After doing the setup mentioned above, I still have to do a manual rebuild on a project that generates a dll into specified dir. Pressing F5 does nothing, I don't have time to find out why... Main thing is its working for me
I had this recently too and I didn't see the answer here. I was changing an MMI to get rid of redundant buttons, and they didn't go away.
Really old legacy code. To make it keep user settings - like language - someone had made it keep the Settings. I was not allowed to change this, they want it like that.
To get rid of the old settings and allow new ones:
open regedit
navigate to HKEY_CURRENT_USER - Software - MyProject - SubProject
here you see Recent File List and Settings.
Delete Settings completely - don't worry, it will make a new one.
Please check is there any old .tlb file present in someother folder. In my case i was using the .tlb file generated using .NET dll and then created the .tlb file using RegAsm. I tried to use the .tlb file in vb6 code, it still refers old code only. After a long search i found same .tlb file older version found in Visual Studio\VB98 folder. I removed it then it worked fine. This may not be relevent for this issue but could give you another way of thinking
There is a scroll bar at the top which has 3 options:
debug
release
configuration manager
Make sure release is selected.
I had to clear browsing data and it worked in my case
I have a solution in Visual Studio that is comprised of 5 projects. The projects build to assemblies (.dll). I have the output path of each project set to \my-web-server\wwwroot\bin, which works fine on one project. In the properties for all of my projects, I have the output path set to the same directory, but when I try building all but one of the projects, I get the error:
Unable to copy file "obj\Release\Index.dll" to "\my-web-server\wwwroot\bin\Index.dll". Access to the path '\my-web-server\wwwroot\bin\Index.dll' is denied.
I assume it could be an issue with permissions, because my organization keeps things locked down, but I have no control over granting permissions. Any help in the right direction is much appreciated.
It must've been something silly. I deleted the .dll manually, then rebuilt. Looks like everything's working normally. Thanks.
The solution for me was to delete everything in bin and obj folders in every project. Just ran this powershell script as described here.
I had the same issue. A copy of Visual Studio (devenv.exe) was still running invisible in the background keeping the particular dll locked.
Delete all DLLs from the bin folder and build the solution.
just had the same issue, built a new project/solution, got it all working and then added to TFS.
Unfortunately I did not clean the build before adding and this meant some files that should not have been under source control were and were then read only(not checked out).
Manually deleting the files before rebuilding fixed the issue.
Most likely a program is running using that library.
This happens to me when running something to debug, and I forget to close it (not attached to IDE debugger).
And since this looks like a website, it is potentially due to the website being hosted from the development build folder, and someone is accessing it.
Similar to what Aequitarum said, it's mostly likely a locked file because it's in use. Since you have multiple projects, you mostly likely have references between them. And since you have all the projects outputting to the same folder any of the referenced projects will most likely get copied more than once if you have those files set to be deployed in the child project. (In a C# web application, you can view the properties of the reference and look at the "Copy Local" property.) And if you have the MsBuild project set to use multiple processors for the build, two child projects are both trying to copy the file at approximately the same time and one is erring out.
It's a very unique situation, but it is possible.
Working solution
Just go to Task Manager and search Detail (if its Win10) and search with your application name (for easy search just look at your windows user id wise)
And right click shows properties. just give the permission like Administrator access.
That's all its working fine for me. ( I was struggling for 1 week and its killed more my time)
It looks like WSearch Service locks up the files and does not release them. I disabled the service on WINDOWS 10 and was able to rebuild the solution.
