我正在爲一所學校的項目工作，我需要創建一個WCF服務，我可以在我的原始解決方案中使用它。爲什麼我的ASP C＃WCF服務不工作？
我通過轉到文件 - >新建項目 - > WCF服務應用程序（添加到解決方案）創建了服務，然後通過在Assignment8解決方案和新引用下右鍵單擊References來添加服務引用。然後我發現解決方案中的服務並添加了產品服務。
我目前得到錯誤：UpdateProduct.aspx.cs上發生在Button1_Click的方法中的if語句行
'Assignment8.Product.ProductClient' does not contain a definition for 'UpdateProduct' and no extension method 'UpdateProduct' accepting a first argument of type 'Assignment8.Product.ProductClient' could be found (are you missing a using directive or an assembly reference?)
錯誤。我究竟做錯了什麼？
這裏是我的文件：
IProduct.cs

using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IProduct
{
[OperationContract]
string GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
[OperationContract]
Boolean UpdateProduct(int productID, string productName, string productDescription, decimal productPrice, decimal productCost);
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class CompositeType
{
bool boolValue = true;
string stringValue = "Hello ";
