title: Using WPF dll's in UWP app
body: <p>I'm writing a UWP app, and for some reason I'm unable to reference <code>PresentationFramework.dll</code>. It contains some WPF controls I want to use (specifically, <code>System.Windows.Controls.DataGrid</code>, but they aren't available under Universal Windows >> Extensions in the reference manager. Why is this, and how can I fix it?</p>
