Trying to add a service reference results in Bad Request (400) in one project, otherwise runs fine

Question

I\'m in a delicate situation: As the title suggests, I can\'t seem to connect to a WCF service I wrapped up in a Windows Service. I followed the tutorial http://msdn.microso

For the beginning you have to find an issue, I mean you need to know what happens on server side. You need to handler all error and log them.

Logging errors

    public class GlobalErrorHanler: IErrorHandler 
    {
        //to use log4net you have to have a proper configuration in you web/app.config
        private static readonly ILog Logger = LogManager.GetLogger(typeof (GlobalErrorHandler));

        public bool HandleError(Exception error)
        {
            //if you host your app on IIS you have to log using log4net for example
            Logger.Error("Error occurred on the service side", error);

            //Console.WriteLine(error.Message); 
            //Console.WriteLine(error.StackTrace);

            return false;
        }

        public void ProvideFault(Exception error, System.ServiceModel.Channels.MessageVersion version, ref System.ServiceModel.Channels.Message fault)
        {
            //you can provide you fault exception here
        }
    }

Then service behavior (inherits Attribute to add possibility to use it as an attribute on service implementation):

public class MyErrorHandlingBehavior : Attribute, IServiceBehavior
{

    public void AddBindingParameters(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {
        return;
    }

    public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
    {
        foreach (ChannelDispatcher disp in serviceHostBase.ChannelDispatchers)
            disp.ErrorHandlers.Add(new GlobalErrorHanler());
    }

    public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
    {        }
}

And extension element to use it in your config:

public class ErrorHandlerExtention: BehaviorExtensionElement
{

    public override Type BehaviorType
    {
        get { return typeof(MyErrorHandlingBehavior); }
    }

    protected override object CreateBehavior()
    {
        return new MyErrorHandlingBehavior();
    }
}

Then add to config file:

This will allow you to get an error. When you have an error get back to the forum.

To turn on tracing you have to add such lines to a config:
