Here is source code for a preliminary Xamarin.iOS binding for Google's ChromeCast
and
Here is C# source code for a simple iOS app that casts a video URL
In order for this to work, you'll need:
- Xamarin.iOS
- Google ChromeCast SDK
- A whitelisted ChromeCast
This is just source code, not a step-by-step walkthrough. Everything associated with this is in beta and I don't want to invest a lot of time making things just so at this point.
You can read an overview of the programming model here.
