Creating a Silverlight 2.0 Application that Consumes a WCF Service - Configuring for Silverlight

(Page 2 of 4 )

The following are the steps to configure the WCF Service to be consumed by the Silverlight 2.0 application. Please understand that the entire following configuration is only for a development environment and the configuration for a production environment might be different.

Change “Service1” to “EmpService” everywhere as follows:

• Using Solution Explorer, right click on “IService1.vb” and rename it to “IEmpService.vb.”

• The above should replace the existing interface “IService1” to “IEmpService” everywhere in the code. If it does not do it automatically, you have to do it manually yourself.

• Using Solution Explorer, right click on “Service1.svc” and rename it to “EmpService.svc.”

• Go to the code-behind of the same file and change the class name “Service1” to “EmpService.”

• Right click on “EmpService.svc” again and select “Open with.”

• Now you have to modify the service file itself. In the “Open with” list, select “Source Code (Text) Editor” and click “OK.”

• Modify the existing line so that it matches the following:

<%@ ServiceHost Language="VB" Debug="true" Service="DemoEmpService.EmpService" CodeBehind="EmpService.svc.vb" %>

• Save all.

Modify “Web.Config” as follows:

• Open “Web.Config” and modify Service model configuration as follows (Fig 03)
  
  

• Add the connection string as follows (modify this according to your environment):

 <connectionStrings>

<add name="cnSample" connectionString="Data Source=.sql2k5;initial catalog=sample;user id=sa;password=eXpress2005"/>

</connectionStrings>

• Save all

Configure a virtual path (using Project properties) and add ClientAccessPolicy.xml as follows:

• Using “Solution Explorer,” right click on “DemoEmpService” project and select “Properties.”

• Go to the “Web” tab and in the “Server” section, select “Use Local IIS Web Server.”

• Provide “http://localhost/DemoEmpService” as the project URL, check on “Override application root” and click on “Create Virtual Directory” (Fig 04).

• Save all.

• Make sure that “DemoEmpService” is listed in IIS and configured with “ASP.NET 2.0” runtime.

• Make sure that both “Anonymous Authentication” and “Integrated Authentication” are enabled for “DemoEmpService” in IIS.

• In your web virtual root (usually c:inetpubwwwroot), create a new file , name it “ClientAccessPolicy.xml” and copy the following code (Fig 05).
