C#

Scott Lilly's Learn C# By Building a Simple RPG Game is the best place to start. It builds a small text adventure with Windows Forms and introduces classes, properties, lists and events one lesson at a time, which suits someone who knows basic syntax but has not built a full program yet. Create a Rogue-like game in C# follows the RogueSharp tutorials, which cover map generation, field of view and turn scheduling for a dungeon crawler.

Building the CoreWiki is a YouTube playlist that builds a wiki-style content management system with ASP.NET Core and Razor Pages, and is the most relevant entry for C# web development today. The two Xamarin tutorials, Create a Blank App with C# and Xamarin and Build iOS Photo Library App with Xamarin and Visual Studio, still explain mobile app structure well, but Microsoft ended Xamarin support in 2024 in favor of .NET MAUI, so expect to translate the setup steps.
