I see that we also do a lookup for other COM attributes in GetDataForComInvocation and GenerateProgIdForType - I think those should be annotated as well, to avoid IL2045 warnings for the following program:

using System.Runtime.InteropServices;

Marshal.GenerateProgIdForType(null);
new ComAwareEventInfo(null, null).AddEventHandler(null, null);

LGTM, thanks!

/ba-g timeouts are unrelated to the changes.

Merging to unblock sdk flow.
