示例1: BehaviorService

//引入命名空间
using System;
using System.ServiceModel;
using System.Transactions;

    Namespace="http://microsoft.wcf.documentation", 
    SessionMode=SessionMode.Required
  )]
  public interface IBehaviorService
  {
    [OperationContract]
    string TxWork(string message);
  }

  // Note: To use the TransactionIsolationLevel property, you 
  // must add a reference to the System.Transactions.dll assembly.
  /* The following service implementation:
   *   -- Processes messages on one thread at a time
   *   -- Creates one service object per session
   *   -- Releases the service object when the transaction commits
   */

    }

     * The following operation-level behaviors are specified:
     *   -- The executing transaction is committed when
     *        the operation completes without an
