New Post: UserControl: XamlParseException

Hi everybody,

I'm a newbie to OxyPlot and WPF. I was able to run this example and adding some more fun stuff in a stand-alone application.
But when I try to make a User Control Library I keep getting a XamlParseException: impossible to load OxyPlot.Wpf, PublicKeyToken=75e952ba404cdbb0

In the main program I simply have an empty window with my control. The xaml in VS renders fine!

I'm using VS 2013 Update 2, Win 7, .net 4 or 4.5 behaves the same.
Oxyplot is 2014.1.318.1

It's probably a stupid trivial error, but I need somebody to point me to the right direction!
Thanks!
