## What it is
RoslynPad is a cross-platform C# code editor and runner built on the Roslyn compiler platform and an Avalonia-based editor. It provides IDE-like features such as completion, diagnostics, code fixes, and real-time script execution without requiring a full IDE.

## Use cases
- run C# scripts quickly without a full IDE
- try out C# code snippets with real-time execution
- get IntelliSense completion and quick info for C# on Linux or macOS
- install NuGet packages and experiment with libraries in a lightweight editor
- write and run file-based C# apps with live diagnostics and code fixes

## When to choose
- you need a lightweight, cross-platform C# scratchpad or script runner
- you want Roslyn-powered IntelliSense and diagnostics outside Visual Studio
- you're on Linux or macOS and need a native C# editor

## When to avoid
- you need full project/solution management, debugging, or refactoring of large codebases
- you require a full IDE experience like Visual Studio or Rider
- you work primarily in languages other than C#
