Completes an asynchronous operation to get a security token.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
When you inherit from the SecurityTokenProvider class you are not required to override the asynchronous methods, as the SecurityTokenProvider base class provides asynchronous support based upon the synchronous methods. Therefore, you are not required to override the method, unless you must provide your own asynchronous implementation.
The EndGetToken method calls the method.
