The following code example shows the use of FaultContractAttribute to specify that the SampleMethod operation can return a SOAP fault with the detail type of GreetingFault.

using System;
using System.Collections.Generic;
using System.Net.Security;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace Microsoft.WCF.Documentation
  public interface ISampleService{
    string SampleMethod(string msg);
  public class GreetingFault
    private string report;

    public GreetingFault(string message)
      this.report = message;

    public string Message
      get { return this.report; }
      set { this.report = value; }

  class SampleService : ISampleService
  #region ISampleService Members

  public string  SampleMethod(string msg)
    Console.WriteLine("Client said: " + msg);
    // Generate intermittent error behavior.
    Random rnd = new Random(DateTime.Now.Millisecond);
    int test = rnd.Next(5);
    if (test % 2 != 0)
      return "The service greets you: " + msg; 
      throw new FaultException<GreetingFault>(new GreetingFault("A Greeting error occurred. You said: " + msg));
