Answer 2

使用消息合约时，您必须遵循某些规则 1.使用Message contract type作为参数时，servicie Operation中只能使用一个参数 [OperationContract的] void SaveEmployeeDetails（EmployeeDetails emp）;

2. Service operation either should return Messagecontract type or it should not return any value

[OperationContract的] EmployeeDetails GetEmployeeDetails（）;

3. Service operation will accept and return only message contract type. Other data types are not allowed.

[OperationContract的] EmployeeDetails ModifyEmployeeDetails（EmployeeDetails emp）;

注意：如果类型同时具有消息和数据合同，则服务操作将仅接受消息合同。
