Calling WCF Service (Hosted in SharePoint 2010) From Silverlight client .

In My previous blog post  I showed how to host custom WCF service inside SharePoint 2010. In this blog post we are going to see how to consume the same service from SilverLight client. here is the link which talks about how to host custom WCF Service in SharePoint 2010 http://mstecharchitect.blogspot.com/2010/03/hosting-wcf-service-inside-sharepoint.html.

Here are steps we are going to follow.

1. First Create a new SilverLight Project.
2. Add WCF Service Reference.
3. Call the WCF Service.

Step 1:

First Fire up VS.NET 2010 and Create SilverLight Application project.

Step 2:

Now add WCF Service Reference to newly created SilverLight project.

Step 3:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SilverlightApplicationCallingWCFsvc
{
    public partial class MainPage :UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            SharePointWCFServiceReference.CustomServiceClient svc = new SharePointWCFServiceReference.CustomServiceClient();
            svc.GetTimeCompleted += new EventHandler<SharePointWCFServiceReference.GetTimeCompletedEventArgs>(svc_GetTimeCompleted); svc.GetTimeAsync(); } void svc_GetTimeCompleted(object sender, SharePointWCFServiceReference.GetTimeCompletedEventArgs e)
        {
            txtfrommoss.Text = e.Result.ToString ();
        }
    }
}

In the above code snippet we are creating  the instance of WCF Serviceclient class and Invoking  the WCF Method. In Silverlight Application the service calls are made as Asynchronous calls. To call GetTime Method  in asynchronous we need to add event Handler for the GetTime Mehtod.

Now Hit F5 and test the app.
