类型“<var>Type Name</var>”中的同步 OperationContract 方法“<var>Method name</var>”与异步 OperationContract 方法“<var>X</var>”和“<var>Y</var>”匹配，因为它们具有相同的操作名称“<var>Z</var>”。当同步 OperationContract 方法与一对异步 OperationContract 方法匹配时，必须在同步 OperationContract 方法上声明其他所有属性。在此情况下，异步 OperationContract 方法“<var>X</var>”有一或多个类型为“X”的属性。要解决此问题，从方法“<var>X</var>”中删除“X”属性(一或多个)。此外，更改其中一个方法的名称将阻止匹配。

The synchronous OperationContract method '<var>Method name</var>' in type '<var>Type Name</var>' was matched with the asynchronous OperationContract methods '<var>X</var>' and '<var>Y</var>' because they have the same operation name '<var>Z</var>'. When a synchronous OperationContract method is matched to a pair of asynchronous OperationContract methods, any additional attributes must be declared on the synchronous OperationContract method. In this case, the asynchronous OperationContract method '<var>X</var>' has one or more attributes of type 'X'. To fix it, remove the 'X' attribute or attributes from method '<var>X</var>'. Alternatively, changing the name of one of the methods will prevent matching.
