title: Why does a Silverlight application show a blank browser screen when created from exported template?
body: <p>I created a <strong>silverlight</strong> app (without website) named <strong>TestApp</strong>, with one TextBox:</p>
  
  <pre><code>&lt;UserControl x:Class="TestApp.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"&gt;
    &lt;Grid x:Name="LayoutRoot"&gt;
          &lt;TextBlock Text="this is a test"/&gt;
    &lt;/Grid&gt;
  &lt;/UserControl&gt;
  </code></pre>
  
  <p>I press <strong>F5</strong> and see "this is a test" in my browser (firefox).</p>
  
  <p>I select <strong>File</strong> | <strong>Export Template</strong> | name it <strong>TestAppTemplate</strong> and <strong>save</strong> it.</p>
  
  <p>I create a <strong>new</strong> silverlight app based on the above template.</p>
  
  <p>The MainPage.xaml has the <strong>exact</strong> same XAML as above.</p>
  
  <p>I press <strong>F5</strong> and see a <strong>blank screen</strong> in my browser.</p>
  
  <p>I look at the <strong>HTML source</strong> of both of these and they are <strong>identical</strong>.</p>
  
  <p><strong>Everything</strong> I have compared in both projects is <strong>identical</strong>.</p>
  
  <p><strong>What do I have to do so that a Silverlight application which is created from my exported template does not show a blank screen?</strong></p>
  
  <p>(creating a WPF application from an exported template like this works fine)</p>
