title: What renders WinForm controls that are hosted in a WPF application?
body: <p>From <a href="http://msdn.microsoft.com/en-us/library/ms742522.aspx" rel="nofollow noreferrer">MSDN article</a> I found out that WinForm controls can be hosted in a WPF application using <code>HwndHost</code>.</p>
  <p>Also, from other internet resources, I found that WPF is rendered using DirectX and WinForm is rendered using GDI+.</p>
  <p>My question is, what renders a WinForm control when the WinForm control is drawn in a WPF application; DirectX, GDI+, or both?</p>
  <p>I have very little experience with both technologies and making baby steps.</p>
  <p>Thank you</p>
