Has anyone been able to communicate using WCF on Windows Phone Series 7 emulator?
I've been trying for the past two days and it's just happening for me. I can get a normal Silverlight control to work in both Silverlight 3 and Silverlight 4, but not the phone version. Here are two versions that I've tried:
Version 1 - Using Async Pattern
BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress("http://localhost/wcf/Authentication.svc");
Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress);
AsyncCallback callback = (result) =>
{
Action<string> write = (str) =>
{
this.Dispatcher.BeginInvoke(delegate
{
//Display something
});
};
try
{
Wcf.IAuthentication auth = result.AsyncState as Wcf.IAuthentication;
Wcf.AuthenticationResponse response = auth.EndLogin(result);
write(response.Success.ToString());
}
catch (Exception ex)
{
write(ex.Message);
System.Diagnostics.Debug.WriteLine(ex.Message);
}
};
auth1.BeginLogin("user0", "test0", callback, auth1);
This version breaks on this line:
Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress);
Throwing System.NotSupportedException. The exception is not very descriptive and the callstack is equally not very helpful:
at System.ServiceModel.DiagnosticUtility.ExceptionUtility.BuildMessage(Exception x)
at System.ServiceModel.DiagnosticUtility.ExceptionUtility.LogException(Exception x)
at System.ServiceModel.DiagnosticUtility.ExceptionUtility.ThrowHelperError(Exception e)
at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address)
at WindowsPhoneApplication2.MainPage.DoLogin()
....
Version 2 - Blocking WCF call
Here is the version that doesn't use the async pattern.
[System.ServiceModel.ServiceContract]
public interface IAuthentication
{
[System.ServiceModel.OperationContract]
AuthenticationResponse Login(string user, string password);
}
public class WcfClientBase<TChannel> : System.ServiceModel.ClientBase<TChannel> where TChannel : class {
public WcfClientBase(string name, bool streaming)
: base(GetBinding(streaming), GetEndpoint(name)) {
ClientCredentials.UserName.UserName = WcfConfig.UserName;
ClientCredentials.UserName.Password = WcfConfig.Password;
}
public WcfClientBase(string name) : this(name, false) {}
private static System.ServiceModel.Channels.Binding GetBinding(bool streaming) {
System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding();
binding.MaxReceivedMessageSize = 1073741824;
if(streaming) {
//binding.TransferMode = System.ServiceModel.TransferMode.Streamed;
}
/*if(XXXURLXXX.StartsWith("https")) {
binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
}*/
return binding;
}
private static System.ServiceModel.EndpointAddress GetEndpoint(string name) {
return new System.ServiceModel.EndpointAddress(WcfConfig.Endpoint + name + ".svc");
}
protected override TChannel CreateChannel()
{
throw new System.NotImplementedException();
}
}
auth.Login("test0", "password0");
This version crashes in System.ServiceModel.ClientBase<TChannel> constructor. The call stack is a bit different:
at System.Reflection.MethodInfo.get_ReturnParameter()
at System.ServiceModel.Description.ServiceReflector.HasNoDisposableParameters(MethodInfo methodInfo)
at System.ServiceModel.Description.TypeLoader.CreateOperationDescription(ContractDescription contractDescription, MethodInfo methodInfo, MessageDirection direction, ContractReflectionInfo reflectionInfo, ContractDescription declaringContract)
at System.ServiceModel.Description.TypeLoader.CreateOperationDescriptions(ContractDescription contractDescription, ContractReflectionInfo reflectionInfo, Type contractToGetMethodsFrom, ContractDescription declaringContract, MessageDirection direction)
at System.ServiceModel.Description.TypeLoader.CreateContractDescription(ServiceContractAttribute contractAttr, Type contractType, Type serviceType, ContractReflectionInfo& reflectionInfo, Object serviceImplementation)
at System.ServiceModel.Description.TypeLoader.LoadContractDescriptionHelper(Type contractType, Type serviceType, Object serviceImplementation)
at System.ServiceModel.Description.TypeLoader.LoadContractDescription(Type contractType)
at System.ServiceModel.ChannelFactory1.CreateDescription()
at System.ServiceModel.ChannelFactory.InitializeEndpoint(Binding binding, EndpointAddress address)
at System.ServiceModel.ChannelFactory1..ctor(Binding binding, EndpointAddress remoteAddress)
at System.ServiceModel.ClientBase1..ctor(Binding binding, EndpointAddress remoteAddress)
at Wcf.WcfClientBase1..ctor(String name, Boolean streaming)
at Wcf.WcfClientBase`1..ctor(String name)
at Wcf.AuthenticationClient..ctor()
at WindowsPhoneApplication2.MainPage.DoLogin()
...
Any ideas?
