Extended Design Guidelines Rules rule set for managed code

 

The Microsoft Extended Design Guideline Rules rule set expands on the basic design guideline rules to maximize the usability and maintainability issues that are reported. Extra emphasis is placed on naming guidelines. You should consider including this rule set if your project includes library code or if you want to enforce the highest standards for writing code that is easy to maintain.

The Extended Design Guideline Rules include all of the Microsoft Basic Design Guideline Rules. The Basic Design Guideline Rules include all of the Microsoft Minimum Recommended Rules. For more information, see Basic Design Guideline Rules rule set for managed code and Managed Recommended Rules rule set for managed code

The following table describes all the rules in the Microsoft Extended Design Guideline Rules rule set.
