How to Share Status Across Social Networking in Windows Phone 7 Via WCF Service


Today, in this article let's play around by implementing an interesting concept often used on a day-to-day basis in Windows Phone. This concept is highly useful for people who become involved with sharing messages across social networking sites. This article clearly demonstrates necessary information conveying to the reader actual illustrations and work with real-time scenarios that they come across when asked to use ShareStatusTask.

So, let's get it started off now.

The Complete Code of IService1.cs looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text; 

namespace Share_Status_App_WCF
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string Status(string a); 
    }
}

The Complete Code of Service1.svc.cs looks like this:   

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace Share_Status_App_WCF
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class Service1 : IService1
    {
         public string Status(string a)
        {
            return "" + a;
        }
    }
}
      

The Complete Code of Web.Config looks like this:

<?xml version="1.0"?>
<
configuration>
     <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior>

 <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->

                    <serviceMetadata httpGetEnabled="true"/>

                    <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->

                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true"/>
    </system.webServer>
</
configuration>

The Output of the Application looks like this:

The Nothing Entered Output of the Application looks like this:
