A simple Xamarin app to describe photos using the Azure computer vision service. This was written during an introduction to Xamarin session at Imperial College London, the slides for which are included in the Slides folder.

This app uses the Xamarin Media Plugin to take a photo, then the Azure Computer Vision Service to generate a description.

1. Head to the Azure Cognitive Services site and click the Try the Computer Vision API button.
2. Log in with an appropriate provider, and get an API key.
3. Open the solution and head to the MainViewModel class in the PhotoDescriber project. In the constructor where the ApiKeyServiceClientCredentials is created, change <your key here> to your API key.
