What role does Visual Studio play in a typical Xamarin development workflow?

Questions in this quiz
  1. What role does Visual Studio play in a typical Xamarin development workflow?
  2. What does it mean that Xamarin apps compile to genuinely "native" code for each platform, rather than running through an interpreted/JavaScript bridge (as some other cross-platform frameworks do)?
  3. What is a "custom renderer" in Xamarin.Forms, and when might a developer need to create one?
  4. What is the general architecture of how Xamarin achieves running C#/.NET code on iOS, given that iOS doesn't natively run .NET/CLR code the way Windows does?
  5. What is data binding in Xamarin.Forms, and what problem does it solve?
  6. What is Xamarin?
  7. What is Xamarin.Essentials (or its .NET MAUI equivalent), and what kind of functionality does it provide?
  8. What is a general tradeoff of Xamarin.Forms' shared, cross-platform UI abstraction compared to writing fully separate native UI per platform (via Xamarin.Android/Xamarin.iOS directly)?
  9. What does "platform-specific code" (via `#if __ANDROID__` / `#if __IOS__` preprocessor directives, or via separate platform project files) allow within an otherwise-shared Xamarin codebase?
  10. What is a reasonable summary of where Xamarin fits today, given Microsoft's direction toward .NET MAUI as its successor?
  11. What is the significance of Xamarin being open-source (built on the open-source Mono runtime, and with Xamarin's own SDK components eventually open-sourced under Microsoft)?
  12. What is the general performance consideration sometimes cited regarding Xamarin.Forms' shared UI abstraction layer compared to writing fully native UI directly?
