Project references both NodaTime (NS 1.x) and Dapper (NS 2.0).

When built WITHOUT <RuntimeIdentifiers> in the .csproj dotnet restore runs to completion and restore is successfull.

When <RuntimeIdentifiers> is set to any valid value AND both packages are referenced/used restore fails with these cryptic messages:

Note that if Dapper / NodaTime are used exclusively dotnet restore while using <RuntimeIdentifiers> runs successfully again....

It looks like NuGet is correctly identifying the downgrades due to how these packages are authored, and the SDK is setting NU1605 to an error.

Getting different packages is expected when using a RID. If the packages brought in by the RID cause problems then it is also a package authoring issue.
