The MainPage.xaml file provides the default UI for your application. When compiled along with its associated code-behind, it forms the MainPage class, from which a MainPage object can be created. If you recall from the previous section, the RootVisual property of the application was set to a new instance of a Page object, thus allowing this class to provide the default UI.

First, notice that the container for the XAML is a UserControl, which is something you might not be familiar with if you are coming from Silverlight 1, which didn t have the .NET programming model. As mentioned earlier, when building Silverlight .NET applications in Visual Studio, you actually build controls that compile into a DLL in an XAP that Silverlight opens and renders. In this case, you can see that this UserControl instance is called SlidingBlocks3.MainPage. SlidingBlocks is the namespace (look back at the project properties to see this), and Page is the name of the class in that namespace. The xmlns and xmlns:x declarations configure the default namespace and the extended namespace, respectively, to be used to validate the XAML. Earlier you saw the x:Class attribute used to define the class for this control, and this is an example of using the extended namespace, which is prefixed by x:. Finally, the width and height are set to the default 400 300. Next comes the root Grid. In Silverlight 3, your root element must be a Container, which in this case is a Grid called LayoutRoot. All elements of your UI design ultimately are children of this node. The code-behind for this XAML is shown here:

If you are familiar with C#, this will look very similar to code you might have used before. Basically, it is a boilerplate class file named Page that inherits from the UserControl type. In the class constructor, the special InitializeComponent() call is used to set everything up. You add your page-specific code to this module, as you ll see in the section titled Building a Silverlight Game later in this chapter, where you create the sliding picture puzzle.
The Web Project
In addition to the control project, the template also creates a Web project that hosts your Silverlight application. This Web project contains two ASPX files: Default.aspx, which is an empty Web Form on which you can build an application; and a test page called <ApplicationName>TestPage.aspx (for example, SlidingBlocks3TestPage.aspx), which contains everything necessary to run Silverlight from ASP.NET. Although Silverlight does not have any server-side dependencies, ASP.NET offers some controls that allow the generation of the client-side JavaScript and HTML necessary to host Silverlight in the browser. The TestPage file includes references to these controls. Following is some of the markup for the ASPX file:
<%@ Page Language="C#" AutoEventWireup="true" %> <%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls" TagPrefix="asp" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Test Page For SlidingBlocks</title> </head> <body style="height:100%;margin:0;"> <form id="form1" runat="server" style="height:100%;"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/SlidingBlocks3.xap"

MinimumVersion="3.0.40307.0" Width="100%" Height="100%" /> </div> </form> </body> </html>
Note that this is an evolving technology, so your version number attributes and public key attributes might differ slightly. Don t worry if your code was generated by the template, you should be in good shape. Notice that there are two ASP.NET controls referenced on this page. The first is the ScriptManager control, which is an artifact of ASP.NET AJAX and is a terrific control that is used to manage the downloading and referencing of all necessary JavaScript libraries at the correct time and in the correct place. The second is the Silverlight control. Notice that it takes the XAP that we discussed earlier as its parameter. This control will generate the correct HTML code to create the <object> that represents Silverlight to the browser. When you run this page, you see that a lot of HTML and JavaScript is generated. Toward the bottom of the code, shown in bold type here, you ll see where Silverlight is created and pointed at the XAP file. Here s a snippet:
<script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(Sys.UI.Silverlight.Control, {"source":"ClientBin/SlidingBlocks3.xap"}, null, null, $get("Xaml1")); }); //]]> </script>
This script is interpreted by the browser to instantiate the Silverlight control. Please note that this code relies on ASP.NET and the ASP.NET Silverlight controls to work properly. If you are instantiating from something other than ASP.NET, you can still use the SDK-based JavaScript tools to instantiate Silverlight. This is covered in depth in 6.
