I am constantly this error in debug mode.
Severity Code Description Project File Line Suppression State Error MSB3027 Could not copy "C:\Users\N3617\Source\Repos\Core\CoreData\ConsoleApp1\obj\Debug\netcoreapp3.1\ConsoleApp1.exe" to "bin\Debug\netcoreapp3.1\ConsoleApp1.exe". Exceeded retry count of 10. Failed. The file is locked by: "ConsoleApp1 (1080)" ConsoleApp1 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets 4643
I had to restart system to get rid off this error. Can anyone tell why is this happening?
It seems an old problem that your project is locked by some other process due to some reasons. You can see this similar issue.
It is complex to explain that but you can try the following steps if you faced them next time:
Suggestion
1) open Task Manager--> shut down ConsoleApp1.exe process, any dotnet process, NET Core Host process or similar process every time when you faced this issue and then build your project again.
2) close VS, delete .vs hidden folder under solution folder, bin and obj folder and then restart VS
3) enter Tools-->Options-->Projects and Solutions-->Build and Run-->set maximum numbers of parallel project builds to 1.
4) uncheck option Use Managed Compatibility Mode under Tools-->Options-->Debugging-->General

I have a Blazor server app working with it in Visual Studio 2022 version 17.3.376.3011 and Windows 11. All of a sudden I get these errors: Could not copy from debug to bin because IISEXPRESS.EXE is locking the file.The exact error message is:
Could not copy "obj\Debug\net6.0\xxx.dll" to "bin\Debug\net6.0\xxx.dll".Exceeded retry count of 10. Failed. The file is locked by: "iisexpress.exe (4892)"
I have tried for solutions including:
Closing VS and try to delete obj and bin folders. Doesn't work since
Bin folder can't be deleted because it is locked.
Exit IISExpress in
system tray and then try to delete Bin (doesn't work still locked)
and open VS to rebuild. Same problem.
Kill IISExpress in Task Manager. Won't work because of permission.
Clean solution and rebuild. Same error still.
The only thing that helped is to restart the computor and then it is released and I can continue working.
Is there someone with a fix for this that I'm grateful.
Error:
Cannot open 'C:\Users\veeru\Documents\Visual Studio
2015\Projects\WCFProject\HelloServiceHost\obj\Debug\HelloServiceHost.exe'
for writing -- 'Access to the path 'C:\Users\veeru\Documents\Visual
Studio
2015\Projects\WCFProject\HelloServiceHost\obj\Debug\HelloServiceHost.exe'
is denied.'
You will get this type of error when you have launched HelloServiceHost.exe directly from output path of VS project and trying to build solution/project while exe instance is still running. Or exe instance is still hanging there in memory because of unknown reason. You can try following steps:
Go to Taskmanager and check if you have instance of HelloServiceHost.exe running there and if its then kill it.
If answer to step 1 is negative then close your Visual Studio and reopen it.
My SQL Server 2012 suddenly stopped working here is all I got in popup message:
could not load file or assembly 'microsoft.visualstudio.shell.ui.internal' or one of its dependencies. An attempt was made to load a program with incorrect format.
I have Repaired using installation CD but no luck.
I had the same problem and fixed by uninstalling the Visual Studio 2010 Shell and installing back. Simply reinstalling doesn't work.
1. Download the Visual Studio 2010 Shell: https://www.microsoft.com/en-us/download/details.aspx?id=1366
2. Run the exe file and click uninstall(or remove).
3. Run the exe file and click install with default settings.
After these steps the Management Studio will work just fine.
I got this error in VS2013 when reparing in the logfille,
[113C:2588][2018-01-20T16:41:54]i000: MUX: ExecuteError: Package (vs_minshellcore) failed: Error Message Id: 1305 ErrorMessage: Error reading from file C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.VisualStudio.Shell.UI.Internal\v4.0_12.0.0.0__b03f5f7f11d50a3a\Microsoft.VisualStudio.Shell.UI.Internal.dll. Verify that the file exists and that you can access it.
and I check the file is exist, and I modify its access authority to complete control to every user account, but this error still occur,
Finally I delete this dll, and find same dll in another Normal Computer with VS , and copy the file paste to the problem computer, and run repair again then pass.
Share my works Microsoft.VisualStudio.Shell.UI.Internal.dll in Here.
But in my case after repair success, vs2013 still got error when opening, so I finally give up and turn to use vs2015, which luckly can work. It is a strange problem.
have this problem also with vs2019 community. I was trying to create the first 2019 project after it is installed. Then I got this. I ran the install exe file, vs_community.exe again in order to repaire it. But I found out that the install program request to restart the pc to finish the last step. Actually I restarted the pc afterwards manually. But I still did it by clicking on the button "restart pc". After the pc is restarted, the problem is gong. I can create project without any error.
I download visual studio code for mac today. I tried to create a simple asp.net 5 web application following these instructions https://code.visualstudio.com/Docs/ASPnet5
When I open my web application folder in visual studio, it says I need to run a restore command.
I ran the dnu restore command just like the instructions tell me but it seems to always fail.
I receive different errors every time I run it. But most of them are like this one:
CACHE https://www.nuget.org/api/v2/package/System.Threading/4.0.10-beta-22816
SharpCompress.Common.ArchiveException: Could not find Zip file Directory at the end of the file. File may be corrupted.
Restore failed
There is a stack trace as well, but for brevity sake I'll omit it for now
Has anyone experienced this?
Try dnu restore --no-cache.
You may also need to remove previously downloaded files - check ~/.dnx/packages. I removed all files from that folder some time before trying the above. Also, see the comments below, if ~/.dnx/runtimes contains unexpected versions removing them may also work. Note that the current runtime version can be controlled using dnvm.
I never saw the NullReference exception, but I was getting the SharpCompress.Common.ArchiveException. I suspect there was a mismatch from what dnu thought was the cache state with the actual cache state (maybe something timed out the first time or something).
Observations:
On our Jenkins build server, we were seeing lots of msbuild.exe processes (~100) hanging around after job completion with around 20mb memory usage and 0% CPU activity.
Builds using different versions of stylecop were intermittently failing:
workspace\packages\StyleCop.MSBuild.4.7.41.0\tools\StyleCop.targets(109,7):
error MSB4131: The "ViolationCount" parameter is not supported by the "StyleCopTask" task.
Verify the parameter exists on the task, and it is a gettable public instance property.
Nuget.exe was intermittently exiting with the following access violation error (0x0000005):
.\workspace\.nuget\nuget install .\workspace\packages.config -o .\workspace\packages"
exited with code -1073741819.
MsBuild was launched in the following way via a Jenkins Matrix job, with 'BuildInParallel' enabled:
`msbuild /t:%Targets% /m
/p:Client=%Client%;LOCAL_BUILD=%LOCAL_BUILD%;BUILD_NUMBER=%BUILD_NUMBER%;
JOB_NAME=%JOB_NAME%;Env=%Env%;Configuration=%Configuration%;Platform=%Platform%;
Clean=%Clean%; %~dp0\_Jenkins\Build.proj`
After a lot of digging around and trying various things to no effect, I eventually ended up creating a new minimal solution which reproduced the issue with very little else going on. The issue turned out to be caused by msbuild's multi-core parallelisation - the 'm' parameter.
The 'm' parameter tells msbuild to spawn "nodes", these will remain alive after the build has ended, and are then re-used by new builds!
The StyleCop 'ViolationCount' error was caused by a given build re-using an old version of the stylecop.dll from another build's workspace, where ViolationCount was not supported. This was odd, because the CI workspace only contained the new version. It seems that once the StyleCop.dll was loaded into a given MsBuild node, it would remain loaded for the next build. I can only assume this is because StyleCop loads some sort of singleton into the nodes processs? This also explains the file-locking between builds.
The nuget access violation crash has now gone (with no other changes), so is evidently related to the above node re-use issue.
As the 'm' parameter defaults to the number of cores - we were seeing 24 msbuild instances created on our build server for a given job.

The fix:
Add the line set MSBUILDDISABLENODEREUSE=1 to the batch file which launches msbuild
Launch msbuild with /m:4 /nr:false
The 'nr' paremeter tells msbuild to not use "Node Reuse" - so msbuild instances are closed after the build is completed and no longer clash with each other - resulting in the above errors.
The 'm' parameter is set to 4 to stop too many nodes spawning per-job
I had the same issue. One old reference I found was in csproj files
<PropertyGroup>
<StyleCopMSBuildTargetsFile>..\packages\StyleCop.MSBuild.4.7.48.0\tools\StyleCop.targets</StyleCopMSBuildTargetsFile>
Also, I deleted the entire "Packages" folder that's located in the same folder as sln file after I closed the visual studio. It triggered VS to rebuild the folder and let go of the cache of the old version of stylecop
I've had the same issue for a while, builds were taking over 6 minutes to finish after some digging I found our it's node reuse fault so adding /m:4 /nr:false fixing my issue immediately
