Message in Chinese (Simplified) (中文(简体))
CallbackBehaviorAttribute 只可以在具有双工协定的终结点上作为一种行为运行。协定“<var>Contract Name</var>”不是双工的,因为它不包含回调操作。
Unlocalized message
CallbackBehaviorAttribute can only be run as a behavior on an endpoint with a duplex contract. Contract '<var>Contract Name</var>' is not duplex, as it contains no callback operations.
