title: Unable to find local resource XAML
body: <p>In my user control <code>XAML</code> I am trying to use an <code>IValueConverter</code> .. I have a class named <code>NullToBoolConverter</code> which implements <code>IValueConverter</code>.</p>
  
  <p>I define my namespace like this:</p>
  
  <pre><code>xmlns:local="clr-namespace:MyApp"
  </code></pre>
  
  <p>In my <code>UserControl.Resources</code>, I am trying to reference this class, like this:</p>
  
  <pre><code>&lt;UserControl.Resources&gt;
      &lt;local:NullToBoolConverter x:Key="IsNull"/&gt;
  &lt;/UserControl.Resources&gt;
  </code></pre>
  
  <p>When I start to type in the name of the class <code>NullToBoolConverter</code>, <em>it appears in the drop down menu in the list of available local classes</em>, but as soon as I select it I get the message: <code>The name "NullToBoolConverter" does not exist in the namespace "clr-namespace:MyApp".</code></p>
  
  <p>Am I doing something wrong here ? Any help is appreciated ..</p>
