[antlr-interest] A bug at C# DLLs?

[Rodrigo C. L.]

hello, thanks for the help..

I did all this throught visual studio with .NET, not Mono. I did
compile the grammar with the jar (3.1.1). I'm going to try with NAnt,
but I'm not confident that it'll work.

Anyway, didn't it ocurred with anyone?

My ASTLabelType is CommonTree. Does it help if I change it?

I'm sorry the urge of the questions. I have kind of a deadline. :(
