title: WPF Designer "Could not create an instance of type"
body: <p>In my UI XAML I'm essentially inheriting from a class "BaseView" that contains functionality common to several forms, however this is preventing the designer from displaying the form: "Could not create instance of type BaseView". The code will compile and run, but it is frustrating not to be able to see the form in the Designer.  Is there a better way?  Thanks. </p>
  
  <p>XAML:</p>
  
  <pre><code>&lt;vw:BaseView 
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:vw="clr-namespace:ReviewClient"   
      x:Class="ReviewClient.MainPage"
  </code></pre>
  
  <p>...</p>
