Visual Studio locked file

Question

I use the latest Visual Studio Community 2017 (15.4). And since i installed Visual Studio (never worked in it before). I have ALWAYS despite version had this issue. After compiling a couple of times i start to see:

Unable to copy file "obj\Debug\afile.exe" to "bin\Debug\afile.exe". The process cannot access the file 'bin\Debug\afile.exe' because it is being used by another process.

I searched around and tried just about everything. Nothing works for me. It can be fine for some time but after a while it starts to show again and i can´t compile.

I run on a Windows 7 OS. I have Avast installed and Comodo Firewall. The project is under SourceTree sourcecontroll. I have excluded the obj and bin path in programs.

I have tried changing AssemblyVersion and AssemblyFileVersion. I have tried uninstalling Avast. I have tried "ProcessExplorer" to find what process is accessing the files (0 match).

I really don´t know what more i can do? This is getting really frustrating when you are testing the code you wrote a couple of seconds ago.

I have seen old threads about this issue. Is there nothing i can do to fix this?

Answer 1

When I had this problem, I solved killing the process VBCSCompiler.exe and everything came back normal.

But after the latest updates of the Visual Studio I do not have more this issue.

To finalize the process, you need execute the command taskkill /F /IM VBCSCompiler.exe in cmd, or search the process in manager process of the Windows.
