Call RoleManagerModule.Dispose when you are finished using the System.Web.Security.RoleManagerModule. The RoleManagerModule.Dispose method leaves the System.Web.Security.RoleManagerModule in an unusable state. After calling RoleManagerModule.Dispose, you must release all references to the System.Web.Security.RoleManagerModule so the memory it occupied can be reclaimed by garbage collection.
This method is not intended to be used directly from your code.
