ServiceHostBase Class

Use the ServiceHostBase class to create hosts that provide a custom programming model. The Windows Communication Foundation (WCF) service programming model uses the ServiceHost class.

Special note for Managed C++ users deriving from this class:

• Put your cleanup code in (On)(Begin)Close (and/or OnAbort), not in a destructor.

• Avoid destructors; they cause the compiler to auto-generate IDisposable.

• Avoid non-reference members; they can cause the compiler to auto-generate IDisposable.

• Avoid finalizers; but if you include one, you should suppress the build warning and call SuppressFinalize(Object) and the finalizer itself from (On)(Begin)Close (and/or OnAbort) to emulate what would have been the auto-generated IDisposable behavior.

This sample uses the ServiceHost class, which is derived from ServiceHostBase.

// Host the service within this EXE console application. 
public static void Main()
{
  using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService)))
  {
    try
    {
      // Open the ServiceHost to start listening for messages.
      serviceHost.Open();

        // The service can now be accessed.
      Console.WriteLine("The service is ready.");
      Console.WriteLine("Press <ENTER> to terminate service.");
      Console.ReadLine();

      // Close the ServiceHost.
      serviceHost.Close();
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine(timeProblem.Message);
      Console.ReadLine();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine(commProblem.Message);
      Console.ReadLine();
    }
  }
}
