C# Tutorials

Dennis Ritchie

The only way to learn a new programming language is by writing programs in it.

Dennis Ritchie

The tutorials in this section are intended to get you started working with C# and in particular the .NET Multi-platform App UI (MAUI). If you have already worked with C# in the past, you should take the opportunity to extend your knowledge of the language. Tha might mean, for example, adding other features into the examples provided here. If you have never worked with C#, this is an opportunity to add one more language to your skillset.

Requirements

If you are using your own computer for these exercises, you will need a working configuration. The exercises assume that you will be using Visual Studio Code (VSCode), although other tools are available such as Visual Studio and Rider. If you want to use an alternative IDE/editor, you need to be prepared to adapt the instructions provided in the tutorials.

You should install .NET 9 for the purposes of this module. The dev-environment tutorial will set up a containerized development environment with .NET 9 SDK, PostgreSQL, and Android tooling pre-configured.
