+
+This is step-by-step guide to setting up your developer environment and building your first WinUI app with the latest tools; WinUI, Windows App SDK, Windows Community ToolKit. Throughout this course, we put these tools into practice by building SnowPal, a word-guessing game. In this SnowPal game, the app selects a word for the user to guess, displaying it as a series of blank spaces where each space represents a letter. The player guesses letters one at a time; for every incorrect guess, part of the SnowPal character is built. If the player guesses all letters before exhausting their turns, they win; otherwise, they lose. By building this SnowPal app step by step, you gain hands-on experience with core development concepts while creating something fun and functional.

 [**.NET Community Toolkit**](https://github.com/CommunityToolkit/dotnet)
 
 The .NET Community Toolkit is a collection of NuGet packages with high-performance helpers, extensions, and APIs designed to enhance .NET development across WinUI, WPF, MAUI, and other .NET applications. A key component is the [MVVM Toolkit](/dotnet/communitytoolkit/mvvm/), a lightweight and modern Model-View-ViewModel (MVVM) library that simplifies app architecture with features like observable properties, commands, and dependency injection. Built for performance and flexibility, the MVVM Toolkit helps you implement MVVM patterns efficiently while keeping your code clean and maintainable.
