title: Which assembly to reference for DataGrid?
body: <p>I made my first WPF control:</p>
  
  <pre><code>&lt;UserControl x:Class="Dealogic.VisualStudio.UI.DatabaseManager.Controls.TargetInstance"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  Height="300" Width="300"&gt;
  &lt;Grid&gt;
      &lt;DataGrid ItemsSource="{Binding Customers}" /&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p></p>
  
  <p>On the DataGrid control it says:
  "the type datagrid was not found, Verify that you are not missing an assembly refernece"</p>
  
  <p>I'm creating the control within a Win Forms app. What assembly to I need to include and how do I do that in XAML?</p>
  
  <p>thanks</p>
