WSTrustChannel.BeginValidate Method (Message, AsyncCallback, Object)

[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.]

Begins an asynchronous operation to send a WS-Trust Validate message to an endpoint using the specified Message object.

Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)


Dim instance As WSTrustChannel
Dim message As Message
Dim callback As AsyncCallback
Dim asyncState As Object
Dim returnValue As IAsyncResult

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


Public Function BeginValidate ( _
    message As Message, _

) As IAsyncResult
public IAsyncResult BeginValidate (
    Message message,

    AsyncCallback callback, 
    Object asyncState
public final function BeginValidate (
    message : Message, 
    callback : AsyncCallback, 
    asyncState : Object
) : IAsyncResult


  • message

  • callback
    The AsyncCallback delegate that receives notification of the completion of the asynchronous validate operation.
  • asyncState
