The third edition of the ECMA C# language specification and the Common Language Infrastructure (CLI) have been approved by the ECMA General Assembly. Check the press release for the juicy quote from my boss.
The introductory chapters of the C# specification read like a tutorial. I recommend those interested in the C# language to read the first few chapters as it has most of what they need.
Mono 184.108.40.206 includes a complete implementation of the new C# specification (written in C# of course) and our runtime contains all the new CLI features required.
We are still missing a few new classes and new methods from the updated class libraries, these should be with us soon.
