Hello,
I just started with the WCF REST Starter Kit.
I created a simple service that return an array of an object.
Using the browser, everything works fine but when I use a WCF client, I get an ArgumentException.
I'm not using IIS and here is the code:
The contract:
[ServiceContract]
public interface IGiftService {
[WebGet(UriTemplate="gifts")]
[OperationContract]
List<Gift> GetGifts();
}
public class GiftService : IGiftService {
public List<Gift> GetGifts() {
return new List<Gift>() {
new Gift() { Name = "1", Price = 1.0 },
new Gift() { Name = "2", Price = 1.0 },
new Gift() { Name = "3", Price = 1.0 }
};
}
}
[DataContract]
public class Gift {
[DataMember]
public string Name { get; set; }
[DataMember]
public double Price { get; set; }
}
To start the service:
WebServiceHost2 host = new WebServiceHost2(
typeof(GiftService),
true,
new Uri("http://localhost:8099/tserverservice"));
host.Open();
Console.WriteLine("Running");
Console.ReadLine();
host.Close();
To start the client:
WebChannelFactory<IGiftService> factory = new WebChannelFactory<IGiftService>(
new Uri("http://localhost:8099/tserverservice"));
IGiftService service = factory.CreateChannel();
List<Gift> list = service.GetGifts();
Console.WriteLine("-> " + list.Count);
foreach (var item in list) {
Console.WriteLine("-> " + item.Name);
}
The server and the client are in the same solution and I'm using the same interface in both (to describe the service contract).
The exception says: "A property with the name 'UriTemplateMatchResults' already exists." and that is the stack trace:
Class firing the exception -> Microsoft.ServiceModel.Web.WrappedOperationSelector
Stack trace:

at Microsoft.VisualStudio.Diagnostics.ServiceModelSink.ServiceMethodResolver..ctor(ContractDescription contract, DispatchRuntime runtime, Message request, InstanceContext instanceContext)
What am I doing wrong?
UPDATE: I disabled the help page and the service is working now. Is it a bug?
host.EnableAutomaticHelpPage = false;
Thank you!
