Arithmetic Operation Using WCF Service Hosted on Windows Phone with Silverlight

Today, in this article let's play around by performing arithmetic operation on windows phone using Silverlight with base as WCF Service.

So, we are here only to do practical implementation rather than much studying theory concepts.

So, I think we all are now good to go and implement this interesting concept.

Let's get started it off now!!!

Let's Now Create New WCF Service Application in .NET 4.0 and carryon with further operations like this:

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 WcfService1
{
    // 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]
        double Add(double a, double b);
        [OperationContract]
        double Sub(double a, double b);
        [OperationContract]
        double Mul(double a, double b);
        [OperationContract]
        double Div(double a, double b);
    }
} 

The Complete Code of Service1.svc 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 WcfService1
{
    // 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 double Add(double a, double b)
        {
            return a + b;
        }
 
        public double Sub(double a, double b)
        {
            return a - b;
        }

        public double Mul(double a, double b)
        {
            return a * b;
        }

        public double Div(double a, double b)
        {
            return a / b;
        }
    }
}

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 name="Application">
          <!-- 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" />
    <services>
      <service name="WcfService1.Service1" behaviorConfiguration="Application">
        <endpoint address="/Simple" binding="basicHttpBinding" contract="WcfService1.IService1">

        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:51779/Service1.svc"/>

          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

Now we're all done with WCF Part, now it's time for us to go and create new Windows Phone Application and we will add it to existing solution folder.

The Complete Code of MainPage.xaml looks like this

The Output of the Application looks like this:

 

The Addition Operation Output of the Application looks like this:

 

The Invalid Output Operation Application looks like this:
