[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,UriTemplate = "/GetProducts")]
List<Product> GetProducts();
}
and this is the impplement method
public List<Product> GetProducts()
{
modelEntities context = new modelEntities();
var productEntity = (from p in context.productEntities select p);
List<Product> products = new List<Product>();
foreach (var item in productEntity)
{

}
return products;
}
