	The code seems fine - there is nothing incorrect about it.

	The thing is that there is nothing in the Reflection.Emit API (which
the compiler uses to set attributes) which lets one set the attributes
for the return type. This is a bug in the .NET SDK 1.0. Mono, on the
other hand, does provide the appropriate methods so if you compiled this
with the Mono runtime, it would compile with no warnings.


	HTH,
