Workbook that fails.

I am able to use UrhoSharp via Nuget in Xamarin.iOS from XS, but a workbook fails with the message: "DllNotFoundException: @rpath/Urho.framework/Urho" 

The Urho I get from Nuget is UrhoSharp.1.1.125

I've attached the workbook. The failure occurs at the last line, when I attempt to instantiate (but not yet run) my subclass of Urho.Application. The Workbook exception I see is:

TargetInvocationException: Exception has been thrown by the target of an invocation.

Yeah. Native libraries in NuGets aren't currently supported (see the bottom of release notes such as https://developer.xamarin.com/releases/inspector/preview/inspector-0.10.0/).

https://github.com/xamarin/Workbooks/tree/master/wpf/PlanetEarth is an Urho workbook that "cheats" by bundling the libraries it needs.

On Mac, you might need to call OpenDynamicLibrary("relative/native/lib/path") in your workbook before #r referencing Urho.dll.
