title: Access namespace not defined exactly in XAML
body: <p>Lets assume my XAML is defined as below with my imported namespace in mycontrols. </p>
  
  <pre><code>&lt;Grid x:Class="LayoutGrid"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:sys="clr-namespace:System;assembly=mscorlib"         
      xmlns:mycontrols="clr-namespace:Predefined.Controls;assembly=UIControls"  
      &gt;
  </code></pre>
  
  <p>If i was to use something defined in the namespace <code>Predefined.Controls</code> then i would simply reference it with its alias <code>mycontrols</code></p>
  
  <p>Example:</p>
  
  <pre><code>&lt;mycontrols:MyCustomButton Name="SubmitButton" /&gt;
  </code></pre>
  
  <p>Now if the namespace <code>Predefined.Controls.CustomTextBoxes</code> also existed, is there a way to use a control inside this namespace without having to add it to the XAML definition at the top?</p>
  
  <p>Something like this??</p>
  
  <pre><code>&lt;mycontrols.CustomTextBoxes:MyCustomTextBox Name="TextBox1" /&gt;
  </code></pre>
