JetBrains has just released ReSharper 4.5!   Some of the key features of this upgrade are:

1. 1. performance and memory usage improvements
2. 2. Solution-wide code inspections (tons of cool tools to find unused params, privates, etc)
3. 3. VB9 support (too bad I’ve been busy moving to C# =])
4. 4. Native MSTest Support (I much prefer NUnit though)

Check it out.  ReSharper is one of the tools I use every day and couldn’t live without…One more day and I’ll be done in Visual Lisp and can actually try out the new release a little more =)
