Saving Contacts in Windows Phone 7 via WCF Service

Today, in this article let's get ready to work out with one concept windows phone. The saving contacts concept is very useful in real time and it's mostly used application by many users. I hope we all have some better idea on how to save contacts on our mobiles. So this article provides a real time example of how to approach if you going to say to code an application as this.

So, let's get it started off.

I think we all are good to go and implement this wonderful concept.

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 Save_Contact_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 FirstName(string a);

        [OperationContract]
        string LastName(string a);

        [OperationContract]
        string JobTitle(string a);

        [OperationContract]
        string WebSite(string a);

        [OperationContract]
        string Company(string a);

        [OperationContract]
        string PhoneNumber(string a);

        [OperationContract]
        string PersonalMail(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 Save_Contact_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 FirstName(string a)
        {
            return "" + a;
        }

        public string LastName(string a)
        {
            return "" + a;
        }

        public string JobTitle(string a)
        {
            return "" + a;
        }

        public string WebSite(string a)
        {
            return "" + a;
        }

        public string Company(string a)
        {
            return "" + a;
        }

        public string PhoneNumber(string a)
        {
            return "" + a;
        }

        public string PersonalMail(string a)
        {
            return "" + a;
        }
    }
}

The Complete Code of WebConfig 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>
