For developers that just cannot get Visual Studio Premium, but still want to use some code analysis tool, I would recommend to take a look into new version of FXCop 10 from Microsoft.

Now it’s a part of official  Microsoft Windows SDK for Windows 7 and .NET Framework 4. You can download it for your version of OS (x86, x64 etc) from http://www.microsoft.com/downloads/details.aspx?familyid=35AEDA01-421D-4BA5-B44B-543DC8C33A20&displaylang=en

After you install SDK, just go to %ProgramFiles%\Microsoft SDKs\Windows\v7.1\Bin\FXCop folder and run setup for FXCop from here.

Ah, and be sure – new version support both .NET 2.0 / 3.5 and latest 4.0!

Hope this helps somebody
