Forgot to change priority: it actually should be Critical/Blocker.

The code is valid and compiles successfully under Windows.

This is indeed a Mono bug, stack trace here:

1 error(s).

Seems Mono is confused when using CreateInstance on a varargs constructor, please file an issue on the Mono bugzilla, thanks!
