If you've been following my whirlwind tour of C# on Channel 9, with episode 4 posted I've now covered the features that I consider to be the major ones — the ones that have the biggest impact on the way we write code. There are other features that were also introduced in C# 2.0, and it is only fair to point out what I left out.

The definitive reference for 2.0 features is the article What's New in the C# 2.0 Language and Compiler, in the Visual C# Getting Started, in the MSDN Library. The topics I opted to not cover are:

• namespace alias qualifier (::)
• external assembly alias
• covariance and contravariance in delegates (you know that you want to know)
• fixed size buffers in unsafe code blocks
• friend assemblies
• inline compiler warning control (#pragma)
• volatile applies to IntPtr and UIntPtr
• and a handful of compiler switches:
• /errorreport
• /keycontainer
• /keyfile
• /langversion
• /linkresource
• /moduleassemblyname
• /pdb
• /platform

Okay, your curiosity should have gotten the better of you by now. Go look up covariance and contravariance in delegates. Then you'll be able to write better code and impress your friends with sesquipedalian verbiage.
