How to: Create a Custom Rule Set
In Visual Studio Premium and Visual Studio Ultimate, you can create and modify a custom rule set to meet specific project needs associated with code analysis. To create a custom rule set, you open one or more standard rule sets in the rule set editor. You can then add or remove specific rules and you can change the action that occurs when code analysis determines that a rule has been violated.
To create a new custom rule set, you save it by using a new file name. The custom rule set is automatically assigned to the project.
Note
If you created or modified a rule set in Visual Studio 2010 Premium and you want to reopen the code project in Visual Studio 2005 or Visual Studio 2008 and run Code Analysis, you have to modify the rule set in Visual Studio 2010 Premium. You can either modify the custom rule set or select one of the preinstalled rule sets and click Customize. Then you can open the project in Visual Studio 2005 or Visual Studio 2008.

In the Add or Remove Rule Sets dialog box, select the rule sets on which you want to base your new rule set and then click OK.
