Completes an asynchronous operation to cancel a security token.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
A security token that can be cancelled, such as one that is issued, allows a client that requested a security token to cancel it when it is done with it.
The method calls EndCancelTokenCore method.Notes to Inheritors
The asynchronous methods, which have a prefix of Begin and End, do not need to be overridden in derived classes. The SecurityTokenProvider base class provides an asynchronous implementation that is based on the synchronous methods.
