This doesn't sound good at all. On the flipside, I've heard and read several people who say Xamarin has been a critical part of their success and like the ecosystem and libraries.

Three years in IT is a long time, so maybe things have changed? I would love to hear other experience reports too.

PS: "Indian code farm developrs (...) low quality garbage (...)" is a gross simplification and generalization which further strengthen negative stereotypes. I advice a different wording to avoid feeding trolls and haters.
