What are your most-recommended Visual Studio preferences?

Question

There are so many little options and settings within Microsoft Visual Studio. Which adjustments do you recommend to others?

Answer 1

Its all about Resharper ;) Gives you tons of shortcuts which are so useful I can no longer work without them. I don't get on with the intellisense though, so I've turned that off.

This is incredibly useful, allows you to write underscores with the space bar when writing long test method names.
