## What it is
SharpLab is a .NET code playground (source of sharplab.io) that shows intermediate steps and results of code compilation, including decompilation to C#, IL, and JIT assembly. It supports C#, Visual Basic, and F# as source languages, with experimental code execution.

## Use cases
- see how C# compiles to IL
- understand what using() desugars to
- decompile C# to see compiler-generated code
- inspect JIT assembly for a code snippet
- quickly run and test small C# snippets online
- compare VB and C# compiled output

## When to choose
- you want to understand how the .NET compiler transforms your code
- you need to inspect IL or JIT assembly for a snippet without setting up tooling
- you want a quick online .NET scratchpad supporting C#, VB, and F#

## When to avoid
- you need a full IDE or complete project compilation
- you need unrestricted code execution or production-grade runtime behavior
- you want to convert VB code to C# via decompilation, which is intentionally verbose

## Facets
- artifact type: application
- maturity: active
- function: compiler, interpreter, developer-tools, parser
- domain: developer-tools, programming-languages, compilers, education
- platform: cross-platform, dotnet
- tags: dotnet, playground, decompiler, il, jit-asm, csharp, fsharp, visual-basic, online-tool, web-server
