'Hello, World!' Walkthrough

The very first thing most developers learns about a new language is, usually, how to say "Hello, World!" in it. The reasons for that are mostly historic, but also because output is the most important part of a program, whether it's written output, visual output or any other form of output. It's what tells the user "hey, this is working and here's the result" or "something went wrong, here's what you can do to improve".

Upon completing this walkthrough, you'll learn how to use the very basics of RSML's API: we won't touch on the advanced parts. This walkthrough can be followed in C# or Visual Basic.

Requirements​

  • .NET: can be any of the versions listed here, but .NET 10.0 is recommended.

Optional tools​

The following tools are not necessary to follow the walkthrough, but make it easier to follow, generally.

  • Visual Studio: version 18 (Visual Studio 2026) is recommended, but Visual Studio 2022 is equally fine. If using Visual Studio, it's recommended to install the official RSML extension.
  • JetBrains Rider: can be used as an alternative to Visual Studio.
  • Visual Studio Code: not an IDE, but can be used as an alternative to Visual Studio and Rider if only the basic code editing is needed. If using VS Code, it's recommended to install the official RSML extension.
