      The following values for ProjectLoadStyle are supported:
      - netstandard2_0:  .NET Standard 2.0
      - net461:          .NET Framework 4.6.1
      - All:             Will build for all platforms

      The choice of targeting .NET Standard 2.0 and .NET Framework 4.6.1 is based on Microsoft's
      recommendations regarding cross-platform targeting:
      - DO start with including a netstandard2.0 target
      - CONSIDER adding a target for net461 when you're offering a netstandard2.0 target.

      See https://docs.microsoft.com/en-us/dotnet/standard/library-guidance/cross-platform-targeting
