Visual Basic .NET is an object-oriented programming language from Microsoft that runs on the .NET runtime. Evolving from the classic Visual Basic, it was relaunched for the .NET platform in 2002 and shares the Common Language Runtime and base class library with C#. It features an approachable, English-like syntax that makes it a popular choice for beginners and for line-of-business application development.
VB.NET is a managed, statically typed language compiled to intermediate language and executed by the .NET runtime, giving it access to the full .NET ecosystem and cross-platform support through modern .NET. It is commonly used for desktop applications, internal tooling, and enterprise software, and it interoperates fully with other .NET languages so libraries can be shared across projects.
Program.vb is the entry point for each run.
Use the Input panel to pipe standard input to your program when it needs data.
Run sends your code to a fresh hosted runtime and streams the result into the output panel.

Type or paste your code into the editor, then click Run (or press Ctrl/Cmd + Enter) to execute it.
Output streams into the console panel, including runtime errors, exit status, and execution time.
Nothing to install and no account to create — code runs in an isolated hosted runtime.
Language-aware autocomplete and IntelliSense suggestions where the editor has a matching language service
Syntax highlighting, with native compiler and runtime errors shown in the console
Bracket matching, auto-indentation, code folding, and a minimap
Multi-cursor editing plus find & replace (Ctrl/Cmd + F)
Full undo/redo history and copy to clipboard
Built on Monaco — the same editor that powers VS Code
