  • For brand-new developers:

    • Start with the Introduction to C# tutorials. These tutorials let you explore the C# language interactively in your browser. From there, you can move on to other tutorials. These tutorials show you how to create C# programs from scratch. The tutorials provide a step-by-step process to create programs. They show the language concepts and how to build C# programs on your own. If you prefer reading overview information first, try the tour of the C# language. It explains the concepts of the C# language. After reading this, you'll have a basic understanding of the language, and be ready to try the tutorials, or build something on your own.
  • For developers new to C#:

    • If you've done development before, but are new to C#, read the tour of the C# language. It covers the basic syntax and structure for the language, and you can use the language tour to contrast C# with other languages you've used. You can also browse the tutorials to try basic C# programs.
  • Experienced C# developers:
