Begins an asynchronous operation to cancel a security token.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
protected virtual IAsyncResult BeginCancelTokenCore( TimeSpan timeout, SecurityToken token, AsyncCallback callback, Object state )
- Type: System.TimeSpan
A TimeSpan that specifies the timeout value for the message that cancels the security token.
- Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous close operation.
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous close operation.
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.Notes to Inheritors
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 need to provide your own asynchronous implementation.
The method is called by the BeginCancelToken method.
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.
