While the code metrics tool gives a pretty good analysis of the code being analyzed, I was wondering if there was any such benchmark on acceptable standards for the following as well:

• Maximum number of types per assembly
• Maximum number of such types that can be accessible
• Maximum number of parameters per method
• Acceptable RFC count
• Acceptable Afferent coupling count
• Acceptable Efferent coupling count

Any other metrics to judge the quality of .Net code by?

Thanks for your time.
