+Subject: [PATCH] Fix full source-build product build when running R2R
+
+See https://github.com/dotnet/source-build/issues/4410
+When building from source, we must set the
+RuntimeIdentifier property explicitly as otherwise
+the SDK defaults to the portable RID.
+
+Also make the SDK aware of the R2R build by updating
+the Known* items in Directory.Build.targets and
+remove the AspNetCore framework references.
+
+Backport: https://github.com/dotnet/fsharp/pull/17259
