WCF: How to actually get to use WSHttpBinding? I get exceptions instead - wcf

Question

I created a WCF Service:
Shared.dll:
[ServiceContract(ConfigurationName = "ICalculator")]
public interface ICalculator
{
[OperationContract()]
int Add(int a, int b);
}
Server:
[ServiceBehavior()]
public class Calculator : ICalculator
{
public int Add(int a, int b) { return a + b; }
}
Client (Attempt #1):
public class CalculatorClient : ClientBase<ICalculator>, ICalculator
{
private static Binding binding = new WSHttpBinding("MyConfig");
private static EndpointAddress remoteAddress = new EndpointAddress(...);
public CalculatorClient() : base(binding, remoteAddress) { }
public int Add(int a, int b)
{
return Channel.Add(a, b); //Exception
}
}
Client (Attempt #2): -- Note: I added a Service Reference instead of creating a CalculatorClient myself (.NET created it for me).
static void Main(string[] args)
{
Binding binding = new WSHttpBinding("MyConfig");
EndpointAddress remoteAddress = new EndpointAddress(...);
CalculatorClient client = new CalculatorClient(binding, remoteAddress);
int result = client.Add(5, 4); //Exception
}
Client (Attempt #3): -- I changed it to be a BasicHttpBinding() instead
static void Main(string[] args)
{
Binding binding = new BasicHttpBinding("MyConfig");
EndpointAddress remoteAddress = new EndpointAddress(...);
CalculatorClient client = new CalculatorClient(binding, remoteAddress);
int result = client.Add(5, 4); //This works!
}
app.config:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="MyConfig" /> <!-- did not add anything to this yet -->
</wsHttpBinding>
</bindings>
</system.serviceModel>
The exception I get is: Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost/CalculatorService.svc. The client and service bindings may be mismatched. I don't see how they can be mismatched when I use a shared dll file between my server and client. The BasicHttpBinding works, just not the WSHttpBinding (I haven't even attempted WS2007HttpBinding.
Exception: [System.ServiceModel.ProtocolException]
{"Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost/CalculatorService.svc. The client and service bindings may be mismatched."}
Inner Exception: [System.Net.WebException]
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..

You need to set the security to be used on the WSHttpBinding
http://msdn.microsoft.com/en-us/library/ms731884(v=VS.90).aspx
Updated with Sample Client/Server WSHttpBinding, default security
Client
class Program
{
static void Main(string[] args)
{
var calcClient = new CalcClient();
int i = 1;
int j = 2;
Console.WriteLine("Result of Adding {0} and {1} is {2}", i, j, calcClient.Add(i, j));
Console.ReadKey();
}
}
public class CalcClient : ICalculator
{
public CalcClient()
{
CalcProxy = ChannelFactory.CreateChannel(new WSHttpBinding(), new EndpointAddress("http://localhost:5050/CalcServer"));
}
ICalculator CalcProxy { get; set; }
public int Add(int a, int b)
{
return CalcProxy.Add(a, b);
}
}
Server
class Program
{
static void Main(string[] args)
{
var host = new ServiceHost(typeof (CalcSvr));
host.AddServiceEndpoint(typeof (ICalculator), new WSHttpBinding(), "http://localhost:5050/CalcServer");
host.Open();
Console.WriteLine("Server Running");
Console.ReadKey();
}
}
