Hello All,

I have created a webpage and trying to integrate a Silverlight control with it. Unfortunately I am getting an error.

XML

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="Home.aspx.cs" Inherits="OnlineEntertainment.Web.WebForm1" %>

<%@ Register Assembly = "System.Web.Silverlight" Namespace="Syste.Web.UI.SilverlightControls" TagPrefix="asp" %>
<%@ Register Assembly = "AjaxConrolToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Silverlight ID="Silverlight1"
Source="C:\Users\Hunter\Documents\Visual Studio 2010\Projects\OnlineEntertainment\OnlineEntertainment.Web\ClientBin"
runat="Server" Height="805px" Width="623px"> </asp:Silverlight>
</asp:Content>

Element 'Silverlight' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.

Is there any specific reason ? I have tried to search for the reference System.Web.Silvelrlight.DLL but it was not present.
I am using Silverlight 5 and Visual Studio 2010.

Thanks and Regards
Anurag

Right off the bat I see that you aren't passing in the name of the xap file for the source. The source parameter must point to the SL xap file you want the runtime to load. But I think you might be declaring the SL runtime object incorrectly. You might review this blog post:

You will probably find it very helpful.

Hello Jason,

I understood your point and tried to modify the source path. However I am wandering that when I am trying to Register the System.Web.Silverlight why I am getting that warning and error. Element Silverlight is not a known element. Web.Config File Missing and all those stuffs.
What I have understood from the link you provided earlier is that there are two controls already shipped with Silverlight 2 SDK. i.e.
Meadia Control and Silverlight Control.

Since this Silverlight Control is not shipped by default with Silverlight 5 SDK I was thinking of that way out. Can you suggest about modifying the web.config file ?
