+         so `dotnet build/publish` without -r targets the current OS.
+         RuntimeInformation.RuntimeIdentifier only exists on .NET 5+, so it's only safe to call
+         when MSBuild itself is hosted on .NET (Core). Visual Studio's bundled MSBuild.exe runs on
+         .NET Framework (MSBuildRuntimeType == 'Full'), where that member doesn't exist and the
+         property function would throw during evaluation, failing solution load. -->
