Releases all resources used by the ClientFormsIdentity.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
Call Dispose when you are finished using the ClientFormsIdentity. The Dispose method leaves the ClientFormsIdentity in an unusable state. After calling Dispose, you must release all references to the ClientFormsIdentity so the garbage collector can reclaim the memory that the ClientFormsIdentity was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.
