I am unsure if this is the correct forum or if I should use the "Xamarin Studio" forum. I downloaded the Shinobi Gauges control from the Component store and attempted to add reference to the DLL in Xamarin Studio on my Mac. I received the exception indicated in the excerpt below. The mono touch library exists in the project and I can use the control in Xcode sample.
