    ByVal state As Object _
) As IAsyncResult

    AppliesTo^ appliesTo,

);

public virtual IAsyncResult BeginIssueSecurityContextToken(
    AppliesTo appliesTo, 
    AsyncCallback callback, 
    System.Object state
);

public function BeginIssueSecurityContextToken(
     appliesTo : AppliesTo, 
     callback : AsyncCallback, 
     state : Object
) : IAsyncResult;

Parameters

• appliesTo
  An AppliesTo that specifies the Web service the requested security token will be used to communicate with.

• 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.
