[Ometa] OMeta# on Mono

[Robert Krahn]

Hi,

I'm trying to run Jeff Moser's OMeta# on Mono. Compiling  
OMetaSharp.dll and OMetaSharp.OMetaCS.dll works fine and the generated  
examples are running as well. However, when I try to parse even a  
simple OMeta grammar with no additional rules an exception is thrown.  
The stack trace is below. I have no experience with C# so any help is  
really appreciated.

Thanks,
Robert
