Yes, that should work. I suspect a bug in the C# target, then. I use  
this in Java and Objective-C targets
quite often.

Unfortunately I have no inkling in what state both the target and its  
developers are right now ;)
Best bet is to ping the perpetrators and try to get them to supply  
you with a fix. 3.0b6 won't be out
within the next two weeks for sure, because Ter is away for that  
time. The next release could well be
away a month or so. :(

cheers,
