Namespace:   System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public WindowsClientCredential Windows { get; }

Property Value

Type: System.ServiceModel.Security.WindowsClientCredential

A WindowsClientCredential that represents the current Windows credential.

You can use the object returned by this property to configure the Windows credential by calling its members, such as AllowNtlm and AllowedImpersonationLevel.

These settings control the Windows credential used during SPNEGO negotiation at either the message or transport level or the properties of Kerberos tokens used for authentication at the message level.

The following code shows how to use the object returned by this property to configure the impersonation level.

  // Create a client object with the given client endpoint configuration.
 CalculatorClient client = new CalculatorClient();
try
  {
      client.ClientCredentials.Windows.AllowedImpersonationLevel 
          = TokenImpersonationLevel.Impersonation;
  }
  catch (TimeoutException timeProblem)
  {
    Console.WriteLine("The service operation timed out. " + timeProblem.Message);
    Console.ReadLine();
    client.Abort();
  }
  catch (CommunicationException commProblem)
  {
    Console.WriteLine("There was a communication problem. " + commProblem.Message + commProblem.StackTrace);
    Console.ReadLine();
    client.Abort();
  }
