Details

The new Static Graph restore will be launching a separate process from MSBuild so it can restore much quicker. However, the logging verbosity will not match the verbosity that the user specified. At the moment, I do not believe there is a way to get the verbosity that the user specified to MSBuild. For now, we only setting "Normal" verbosity

Other suggested things

Verbose Logs

Please include verbose logs (NuGet.exe -verbosity detailed | dotnet.exe --verbosity diag | etc...)
