Jenkins not restoring NuGet packages with new MSBuild restore target

Question

We have a .net full framework WPF application that we\'ve moved from .net 4.6.2 to 4.7.1 along with changing to PackageReference in the csp

Answer 1

For us it was indeed an issue with bitness!

The problem specifically is that MSBuild is actually looking for the nuget packages in the following directory:

C:\Windows\SysWOW64\config\systemprofile\.nuget\packages

Even though the logs actually say:

C:\Windows\System32\config\systemprofile\.nuget\packages

Because the msbuild being called is a 32-bit process running on a 64-bit platform, when it looks in System32, it's actually looking into SysWOW64.

This is done by file system redirection.

The solution for us was to simply call the 64-bit version of MSBuild, located at:

C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin\amd64\MSBuild.exe

Notice the amd64 in the path.
