Message in Chinese (Traditional) (中文（繁體）)
不支援回呼方法 <var>Method name</var>。若方法未以 OperationContractAttribute 標示，或介面類型並非 ServiceContractAttribute 的 CallbackContract 目標，便會發生此一狀況。
Unlocalized message
Callback method <var>Method name</var> is not supported, this can happen if the method is not marked with OperationContractAttribute or if its interface type is not the target of the ServiceContractAttribute's CallbackContract.
