public IAsyncResult BeginCancelToken(
	TimeSpan timeout,
	SecurityToken token,
	AsyncCallback callback,
	Object state
)

Parameters

timeout
Type: System.TimeSpan

A TimeSpan that specifies the timeout value for the message that cancels the security token.

token
Type: System.IdentityModel.Tokens.SecurityToken

The SecurityToken to cancel.

callback
Type: System.AsyncCallback

The AsyncCallback delegate that receives notification of the completion of the asynchronous close operation.

state
Type: System.Object

An object, specified by the application, that contains state information associated with the asynchronous close operation.

Return Value

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous cancel 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 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.
