[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 open a communication object within a specified interval of time.

Namespace: Microsoft.IdentityModel.Protocols.WSTrust
Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)

Usage

'Usage
Dim instance As WSTrustChannel
Dim timeout As TimeSpan
Dim callback As AsyncCallback
Dim state As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginOpen(timeout, callback, state)

Syntax

'Declaration
Public Function BeginOpen ( _
    timeout As TimeSpan, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult

public IAsyncResult BeginOpen (
    TimeSpan timeout,
    AsyncCallback callback,
    Object state
)

public:
virtual IAsyncResult^ BeginOpen (
    TimeSpan timeout, 
    AsyncCallback^ callback, 
    Object^ state
) sealed

public final IAsyncResult BeginOpen (
    TimeSpan timeout, 
    AsyncCallback callback, 
    Object state
)

public final function BeginOpen (
    timeout : TimeSpan, 
    callback : AsyncCallback, 
    state : Object
) : IAsyncResult

Parameters

timeout
The TimeSpan that specifies how long the open operation has to complete before timing out.

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

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

Return Value

The IAsyncResult that references the asynchronous open operation.
