Visual Studio 2010 Developer Edition Features

Can anyone tell me a brief summary about the features of VSTS 2010.

I want a brief introduction on : Class Designer, Static Code Analysis, Code Profiling, Unit Testing with code coverage, Test Impact Analysis and Intellitrace.开发者_StackOverflow中文版

With some Googling:

• Class Designer
• Static Code Analysis
• Code Profiling (Ultimate and Premium only)
• Unit Testing with code coverage (Not 2010 per se, but could be useful)
• Test Impact Analysis
• Intellitrace (Ultimate only)
