I have recently upgraded to VS2010, and overall I must say that I'm very impressed. I used to use ReSharper when working with VS2008, but I have found that many of it's features have been incorporated into VS2010.
One of the features I like the most is the CTRL+, command which lets you navigate to a class or method by writing part of its name.
However, I have not had the time to explore all the new features, so I'd be really greatful if some of you would share the ones you like most.

I really like Call Hierarchies
With Control+K and Control+T you can navigate the code likes reflector does but with the source code

Also a great feature is T-SQL IntelliSense
A long requested feature that will become really :)
