Cannot load ClassDiagram.cd URI formats are not supported
<p>When I create a new Class Diagram in my ASP.NET Application C# it gives me an error message that says:</p>

<pre><code>(Cannot load 'C:\Users\...\...\App_Code\ClassDiagram.cd': URI formats are not supported)
</code></pre>

<p>I don't have any classes in my ASP.NET project.</p>
