Controller.Dispose Method (Boolean)
Releases unmanaged resources and optionally releases managed resources.
Assembly: System.Web.Mvc (in System.Web.Mvc.dll)
The ASP.NET MVC framework calls Dispose when the request has completed processing. Developers typically do not have to call Dispose. If you derive a class from Controller and the derived class uses unmanaged memory, managed operating-system resources (such as files), or COM objects, you should implement Dispose to clean up these resources. You should also call the Dispose method of the base class. The Dispose method leaves the Controller instance in an unusable state. After you call Dispose, you must release all references to the Controller instance so that the garbage collector can reclaim the memory that the Controller instance was occupying.
