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
