+Subject: [PATCH] Include netcorapp5.0 versions in libraries nupkgs
+
+Assets for netcoreapp3.0 are not built in source-build because we don't
+have references for past netcoreapp versions.  That leaves the packages
+built by the libraries build with a placeholder for netcoreapp3.0, which
+causes issues with consumption of these packages in dependent repos.
+Packages for netcoreapp5.0 are built but not packaged by design.  This
+patch includes these assets in the packages built by the libraries
+build, only for the source-build build.
