類型 '<var>Type Name</var>' 的同步 OperationContract 方法 '<var>Method name</var>' 符合非同步 OperationContract 方法 '<var>X</var>' 與 '<var>Y</var>'，因為它們具有相同的作業名稱 '<var>Z</var>'。當同步 OperationContract 方法符合一對非同步 OperationContract 方法時，兩個 OperationContract 必須定義相同的傳回類型。在此例中，傳回類型不同。若要修正此問題，請確認方法 '<var>Method name</var>' 與方法 '<var>Y</var>' 具有相同的傳回類型。另一種方式則是變更其中一種方法的名稱，便可避免相符的情況。

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, the two OperationContracts must define the same return type. In this case, the return types are different. To fix it, ensure that method '<var>Method name</var>' and method '<var>Y</var>' have the same return type. Alternatively, changing the name of one of the methods will prevent matching.
