C# Cross-Platform Development

This is the repository for the LinkedIn Learning course C# Cross-Platform Development. The full course is available from LinkedIn Learning.

In this course, learn the fundamentals of building cross-platform C# apps that work on Android, macOS/iOS, and Windows while leveraging .NET MAUI. Instructor Jesse Freeman shows you core concepts like setting up a cross-platform dev environment, building simple UI, navigating between app screens (pages), and implementing MVVM concepts with data binding XAML. Follow along with Jesse as he shows you how to apply what you’ve learned toward creating a simple note-taking app, and covers the skills you need to know to get started building cross-platform C# apps on your own.

Instructions

This repository uses a branch structure to correspond with different lessons in the course. The branches are named in the format lesson-CHAPTER#.MOVIE#, where CHAPTER# is the chapter number and MOVIE# is the video number in that chapter. You can switch to a specific branch using the branch pop-up menu in GitHub or by adding /tree/BRANCH_NAME to the URL.
