C:\Program Files\dotnet\sdk\10.0.101\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(109,5): error NETSDK1013: The TargetFramework value '' was not recognized. It may be misspelled. If not, then the TargetFrameworkIdentifier and/or TargetFrameworkVersion properties must be specified explicitly.
In larger solutions, this also generates:
The "MSBuild" task returned false but did not log an error
Trigger Conditions
- Project 1 depends on Project 2
- Project 1 sets TargetFrameworks (actual number of frameworks does not matter)
- Project 1 sets GeneratePackageOnBuild to true

- Both projects use Nerdbank.GitVersioning
- Build in Visual Studio
