I'm currently in the process of writing a programming language which extends C# mainly by adding custom operators and keywords.
I have found the grammar file for c# 4 in http://antlrcsharp.codeplex.com/ but cannot find any examples on how to import this file in my own grammar file.
Can anyone provide some examples or point me to other projects which archive the same thing?
If you want to extend c# that means you're doing a DSL?
Check this one out Irony from codeplex, Hanselman explains it better
