Begins an asynchronous operation to cancel a security token.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
public IAsyncResult BeginCancelToken( 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
The BeginCancelTokenCore method is called by the 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.
