Microsoft has released Source Analysis / StyleCop recently.  Where FxCop allows you to perform analysis on compiled binaries, StyleCop analyzes your source code directly.  There seems to be a focus on the partial design, layout and documentation.  A good bit of the information is taken away after the compile and cannot be analyzed by FxCop. 

 This will help to produce more readable, consistent code and will help some development groups standardize / enforce coding guidelines.  It appears some of the rules are not configurable and might take some time to get used to. 

You can download the code from the following path:
