Can't able to Run the basic Silverlight application

Question

Hi,
When I try to run a simple, basic Silverlight application, I got the following error:

Can't find the TestPage.html, Make sure the path or internet address is correct.

Here is my XAML code:

<UserControl x:Class="HelloWorld.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
  <Grid x:Name="LayoutRoot" Background="White">
        <TextBlock Text="Hello, World!" />    
  </Grid>
</UserControl>

What could be the reason for this? Any help would be greatly appreciated.

Thanks.

This sounds like an issue with your project setup. Make sure your ASP.NET project is correctly set with your Silverlight project as a contained Silverlight app. Also you will want to check that in the Project Properties the Startup Item is set to an existing page. It may not be TestPage.html.
