📦 NuGet & MAUI Community Toolkit in .NET MAUI

In .NET MAUI, NuGet is the primary package manager used to integrate external libraries, while the MAUI Community Toolkit is the most essential "must-have" library for most developers.

🧰 The .NET MAUI Community Toolkit

This is a community-driven, open-source library backed by Microsoft that provides a collection of reusable elements not included in the standard MAUI SDK.

✨ Key Features:

• Custom Views: Includes advanced UI components like Expander, DockLayout, and DrawingView.
• Behaviors: Reusable logic for tasks like input validation (e.g., email or numeric checks).
• Converters: Simplifies XAML data binding by converting types on the fly (e.g., InvertedBoolConverter).
• MediaElement: A powerful control for playing audio and video across all platforms.
• Setup Requirement: To use the toolkit, you must initialize it in your MauiProgram.cs file using the UseMauiCommunityToolkit method.
