Answer 1

What helped me was the issue described in https://github.com/NuGet/Home/issues/6918 and the workaround described from AndrewGretton.

1. Download and install the .NET 4.7.2 runtime (not SDK) from https://www.microsoft.com/net/download/dotnet-framework-runtime on the build agent
2. Reboot the agent
