با سلام
من یه کلاس و یه اینترفیس و یه wcf service اضافه کردم به این صورت:
Class :
using System.Runtime.Serialization;
namespace SilverlightApplication16.Web
{
[DataContract]
public class Product
{
[DataMember]
public int ProductId { get; set; }
[DataMember]
public string ProductName { get; set; }
}
}
Interface:
using System.Collections.Generic;
using System.ServiceModel;
namespace SilverlightApplication16.Web
{
[ServiceContract]
public interface IProductServiceContract
{
[OperationContract]
List<Product> GetProductsList();
}
}
اینم توی wcf service که اسمش products.svc گذاشتم وارد کردم :
using System.Collections.Generic;
using System.ServiceModel.Activation;
namespace SilverlightApplication16.Web
{
[AspNetCompatibilityRequirements(RequirementsMode
= AspNetCompatibilityRequirementsMode.Allowed)]
public class Products : IProductServiceContract
{
public List<Product> GetProductsList()
{
return
new List<Product>
{
new Product
{
ProductId = 1,
ProductName = "CD"
},
new Product
{
ProductId = 2,
ProductName = "DVD"
},
new Product
{
ProductId = 3,
ProductName = "RAM"
}
};
}
}
}
اینم توی قسمت web.conifig:

اینارو دقیقا روی کتاب آموزشی انجام دادم
در آخر هر وفتی add service میکنم پیدا میکنه اما هرکاری می کنم ادد نمیشه error میده :گریه:
این خطا رو میده :

Metadata contains a reference that cannot be resolved: 'http://localhost:38886/Products.svc'.
An error occurred while receiving the HTTP response to http://localhost:38886/Products.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
The underlying connection was closed: An unexpected error occurred on a receive.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
An existing connection was forcibly closed by the remote host
If the service is defined in the current solution, try building the solution and adding the service reference again.
