Windows Phone 8中的System.ServiceModel发生了什么？

Question

I'm working on cross-platform application for all mobile and desktop platforms. It's all in C#. I'm working in Visual Studio using Xamarin . It's a client-server app, so I use WCF.

Inspired by Miguel Castro: Extreme WCF I divided my solution into WinForms client, Proxy , Contracts , Services and Console server host. But projects like Proxy or Contracts must be created as PCL (Portable Class Library) and here is my problem - I can't use System.ServiceModel in PCL with Windows 10 or Windows Phone. What's going on? Why?

What's the best walkaround?

EDIT: I guess there is no problem with Windows Universal 10 , only with Windows Phone 8 . When I check Windows 10, it automatically check back to Windows 8 . VS says: The following will be automatically targeted because the support the same set of portable APIs: Windows 8

EDIT2: To be even more clear, I'm struggling implementing this (below) in Portable Class Libiray with checked Windows Phone 8 :

using System.ServiceModel;

namespace Contracts
{
    [ServiceContract]
    public interface IMyService
    {
        [OperationContract]
        int GetSomething();
    }
}

Answer 1

Take a look here for references on which APIs are supported on the Universal Windows Platform.

You can consume WCF services from Windows Phone 8 (as detailed here ) but I am not able to find any documentation that supports hosting WCF services from Windows Phone 8.
