嘗試向Silverlight 4添加新的Web服務時收到此錯誤。我已經在數據訪問對象層中打開了客戶端並擁有業務邏輯準備致電該服務。顯示的錯誤輸出與Windows批處理文件運行有關，該批處理文件運行應該生成調用新的Web服務所必需的文件。我已到處尋找解決方案，並試圖將服務引用類型更改爲通用列表，並取消選中另一個解決方案中指示的「通用程序集中的重用類型」（通過在解決方案資源管理器中右鍵單擊服務引用實例在VS 2010中選擇服務參考設置。） 錯誤：無法導入wsdl：binding和錯誤：無法導入wsdl：porttype繼續顯示。任何輸入woulb將不勝感激。嘗試添加silverlight服務時出現「無法導入wsdl：binding」錯誤

Error: Cannot import wsdl:portType
Detail: An exception was thrown while running a WSDL import extension:
System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: ISerializable type with data contract name 'PropertyChangedEventHandler' in namespace 'http://schemas.datacontract.org/2004/07/System.ComponentModel' cannot be imported. The data contract namespace cannot be customized for ISerializable types and the generated namespace 'AccessPoint.WcfServices.ServiceWcfS' does not match the required CLR namespace 'System.ComponentModel'. Check if the required namespace has been mapped to a different data contract namespace and consider mapping it explicitly using the namespaces collection.
