備註

處理器依訂閱順序同步執行。 執行非同步工作的驗證器會保持其處理程序同步，並透過 註冊非同步驗證器，例如(sender, args) => args.AddAsyncValidator(token => ValidateAsyncCore(token))。AddAsyncValidator(Func<CancellationToken,Task>) ValidateAsync(CancellationToken)呼叫所有註冊驗證者並等待產生的任務;Validate()當處理器登錄非同步工作時，擲出。InvalidOperationException 不要使用處理器 async void ：其工作不會被等待，且會被悄悄跳過。
