'Usage
Public Class securityContextTokenServiceClientImplementation
    Inherits SecurityContextTokenServiceClient
        Protected Overrides Function BeginRequestSecurityContextToken(appliesTo As AppliesTo, _
            callback As AsyncCallback, _

Syntax

'Declaration
Protected Function BeginRequestSecurityContextToken( _
    ByVal appliesTo As AppliesTo, _
    ByVal callback As AsyncCallback, _
    ByVal state As Object _
) As IAsyncResult

protected IAsyncResult BeginRequestSecurityContextToken(
    AppliesTo appliesTo, 
    AsyncCallback callback, 
    object state
);

protected:
IAsyncResult^ BeginRequestSecurityContextToken(
    AppliesTo^ appliesTo,
    AsyncCallback^ callback,
    Object^ state
);

protected IAsyncResult BeginRequestSecurityContextToken(
    AppliesTo appliesTo, 
    AsyncCallback callback, 
    System.Object state
);

protected function BeginRequestSecurityContextToken(
     appliesTo : AppliesTo, 
     callback : AsyncCallback, 
     state : Object
) : IAsyncResult;

Parameters

• appliesTo
  An AppliesTo that specifies the Web service.

• callback
  An AsyncCallback that is called when the asynchronous operation is completed. If callback is null, the delegate is not called.

• state
  An object that contains state information for this request.

Return Value

The SecurityContextToken issued by the security token service.

Remarks

The SecurityContextToken issued by the security token service is used to exchange SOAP messages with the Web service that is specified by the appliesTo parameter

To request a SecurityContextToken security token, call one of the IssueSecurityContextToken overloads.

When the issuerToken parameter is null, the RequestSecurityContextToken method expects the SecurityContextToken to be returned within a <ProofToken> element.
