Last week I did a presentation on Xamarin Dev Days here in Ottawa, the presentation was on Introduction to Xamarin, unfortunately my demo did not work, the demo gods were not with me that day 🙁
The demo code uses Microsoft Cognitive Service Bing Search to search for images to display on a mobile phone. Mainly I was doing a demo on the Android platform. The code base is on Github

The slides for my presentation are located here.

I also did another demo for Carleton University Business Program on Xamarin and if you wish to see more Xamarin related article please let me know 🙂
