This is a preview of a new Reflector Addin that computes various CodeMetrics on .Net assemblies. The excellent Reflector API makes it very easy to do this kind of things. Here are the metrics that I plan to implement :

• Counting metrics: Module/Assembly, Type/Module, Method/Type, etc...
• IL counting metrics: IL/Method, LocalVariables/Method, ExceptionHandlers/Method, etc...
• IL flow graph metrics: components, cyclomatic complexity,
• Method graph: methodrank, callers, callees, components, distance from entry point,
• Type graph: type rank, inherance level, etc...

I have not done an extensive research on the subject so I might forget a lot of them, suggestions and links welcome.

Note that this uses a plugin architecture so that anyone can write and use his own metric.
