I say and I repeat it:
You can not work with Visual Studio but have ReSharper
The phrase is similar to the case of Team Foundation
You can not work with Team Foundation Server without the TFS Power Tools
Visual Studio 11 and Team Foundation 11 are in Beta mode, but that does not mean that the guys from Redmond put the batteries and send us a version of the specific PowerTools for TFS11.
The Power Tools do not have anything new or new tool (this is now ). In the same you will find classic Team Process Editor, Best Practices Analyzer, etc.
This is a good one.
