• Overview of C# 3.0

Yes that's a good start. You can also go over any kind of "what's new in C# 3.0" page, like this one from MSDN.

I can recommend that you have a look at C# in depth by Jon Skeet too. Very good book. :-)

You could look at this stack overflow question. It is not C# 3.0 specific, but contains a fair number of features which are very useful, and not known to all programmers.

There are a number of now widely used features of C# 3 that one "should" learn. That said, what you learned while using C# 2 will be just as applicable under C# 3.

The more common C# 3 features that one might encounter when reviewing other's code, wish to understand and ultimately adopt are:

• Automatically Implemented Properties
• Lambda Expressions
• Linq
• Object Initializers
