UWP/XAML Controls are not present

[kutuup]

After installing the MyToolKit.Extended package via NuGet, none of the XAML controls are present, and pointing the toolbox to the .dll finds no valid controls to place on the toolbox.

To be honest, i never used the ctrls via toolbox, just insert the tag and add the namespace... not sure wherher the controls still works with the latest uwp version
