[Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework. The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

'Usage
Dim instance As IWSTrustContract
Dim message As Message
Dim callback As AsyncCallback
Dim asyncState As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginCancel(message, callback, asyncState)

Syntax

'Declaration
<OperationContractAttribute(AsyncPattern:=True, Name:="Cancel", Action:="*", ReplyAction:="*")> _
Function BeginCancel ( _
    message As Message, _
    callback As AsyncCallback, _
    asyncState As Object _
) As IAsyncResult

[OperationContractAttribute(AsyncPattern=true, Name="Cancel", Action="*", ReplyAction="*")] 
IAsyncResult BeginCancel (
    Message message,
    AsyncCallback callback,
    Object asyncState
)

[OperationContractAttribute(AsyncPattern=true, Name=L"Cancel", Action=L"*", ReplyAction=L"*")] 
IAsyncResult^ BeginCancel (
    Message^ message, 
    AsyncCallback^ callback, 
    Object^ asyncState
)

/** @attribute OperationContractAttribute(AsyncPattern=true, Name="Cancel", Action="*", ReplyAction="*") */ 
IAsyncResult BeginCancel (
    Message message, 
    AsyncCallback callback, 
    Object asyncState
)

OperationContractAttribute(AsyncPattern=true, Name="Cancel", Action="*", ReplyAction="*") 
function BeginCancel (
    message : Message, 
    callback : AsyncCallback, 
    asyncState : Object
) : IAsyncResult

Parameters

message
A Message that represents the request message, which contains the RST.
