To create and test this simple Web Service we have used the Visual Studio Development Server. This section describes how to deploy the service using IIS.

To deploy the service using IIS:

  • Open the RDFWebDemo project in Visual Studio, go to the

    Project

    menu and select RDFWebDemo

    Properties

    .

  • Select the

    Web

    tab and scroll down to the

    Servers

    section. Select

    Use local IIS Server

    . The project URL defaults to using localhost.

  • Click the

    Create Virtual Directory

    button then check that the Service works on localhost.

  • Build the project then start without debugging (ctrl F5).

The start page that you see when you test the service will look the same as before but the address in the browser bar will be something like http://example.com/RDFWebDemo1/WebDataService1.svc/. You can now access your service remotely using the hostname or IP address of your server.

If at this point you get an Access is denied error, 401.3, then you will need to add the Internet Guest Account (IUSR_XXX where XXX is your computer name) to the users allowed to access the folder containing the RDFWebDemo project.

You will now need to modify RDFWebApp to access the service at the new address. At the same time we will also change RDFWebApp so that it too is deployed using IIS

  • Open The RDFWebApp project in Visual Studio.

  • Go to the

    Project

    menu and select RDFWebApp

    Properties

    .

  • Select the

    Web

    tab and scroll down to the

    Servers

    section. Select

    Use local IIS Server

    . The project URL defaults to using localhost.

  • Click the

    Create Virtual Directory

    button. The web application will then run on the local IIS.

    DemoModel.DemoEntities svc = new DemoModel.DemoEntities(new Uri("http://example.com/WebDataService1.svc"));
    

    to

    DemoModel.DemoEntities svc = new DemoModel.DemoEntities(new Uri("http://example.com/RDFWebDemo/WebDataService1.svc/"));
    
  • To reference the web service running on IIS you will need to edit Default.aspx.cs. Change

  • Build the project then start without debugging (ctrl F5).

The web application is accessible on http://example.com/RDFWebApp/Default.aspx and can also be accessed using the hostname or IP address of you server e.g. http://192.168.7.129/RDFWebApp/Default.aspx

The next example shows you how to quickly create an ADO.Net Data Service that exposes RDF data in Virtuoso and how to create a basic Web application to consume that service. The next step is to create a Silverlight Application to consume the same service .
