Description

Design IServiceCollection extension methods that enable easy registration of AI services in .NET MAUI applications with dependency injection.

Goals

• Make it trivial to add AI to a MAUI app (1-2 lines in MauiProgram.cs)
• Support progressive disclosure (simple by default, powerful when needed)
• Follow .NET DI conventions
• Enable platform-agnostic code while allowing platform-specific overrides

Design Proposal

Proposal PR can be found here: #32545

Discussion Points

1. Which API style should we use?
2. Should platform detection be compile-time or runtime?
3. Should we expose platform-specific methods (e.g., AddAppleIntelligenceChatClient())?
4. How should we structure configuration options?
5. What service lifetime should be used (Singleton recommended)?
