I have a solution targetting .netframework 3.5 and getting build in VS2019.

I am able to build the solution using msbuild. Now days I am trying to create a image to build project successfully inside the container.

My DockerFile looks like as given below:

Use a specific tagged image. Tags can be changed, though that is unlikely for most images.

You could also use the immutable tag @sha256:324e9ab7262331ebb16a4100d0fb1cfb804395a766e3bb1806c62989d1fc1326

Restore the default Windows shell for correct batch processing.

SHELL ["cmd", "/S", "/C"]

Install .NET Fx 3.5

Download collect.exe in case of an install failure.

Use the latest release channel. For more control, specify the location of an internal layout.

SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"] WORKDIR /src

Define the entry point for the Docker container.

This entry point starts the developer command prompt and launches the PowerShell shell.

ENTRYPOINT ["C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\Common7\Tools\VsDevCmd.bat", "&&", "powershell.exe", "-NoLogo", "-ExecutionPolicy", "Bypass"] But build is getting failed saying

(CleanupTemporaryTargetAssembly target) -> C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.WinFx.targets(480,10): error MSB3061: Unable to delete file "obj\x86\Release\TestA.dll". Access to the path 'C:\src\Repo\TestProject\obj\x86\Release \TestA.dll' is denied. [C:\src\Repo\TestProject\TestA.csproj]

I tried to delete within container also, its not allowed. There have been discussion around the similar problem but couldn't get concrete root cause and solution. Specially when I am able to build it outside the container in developer command prompt..
