and should be solved (maybe) with this pull req: https://github.com/dotnet/roslyn/pull/53304

This is won't be fixed by updating the decompiler; the root cause is that VS doesn't initialize the type system with a correct set of reference assemblies. As a result the decompiler type system cannot find type System.Array, which prevents the array transforms from working, which in turn prevents the dynamic transform from working.
