[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.]

Dim instance As WSTrustChannel
Dim rst As RequestSecurityToken
Dim callback As AsyncCallback
Dim state As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginValidate(rst, callback, state)

Syntax

'Declaration
Public Function BeginValidate ( _
    rst As RequestSecurityToken, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult

public IAsyncResult BeginValidate (
    RequestSecurityToken rst,
    AsyncCallback callback,
    Object state
)

public:
virtual IAsyncResult^ BeginValidate (
    RequestSecurityToken^ rst, 
    AsyncCallback^ callback, 
    Object^ state
) sealed

    callback : AsyncCallback, 
    state : Object
) : IAsyncResult

Parameters

rst
