## What it is
FastColoredTextBox is a .NET text editor component with fast, customizable syntax highlighting. It supports regex-based styling, word wrap, find/replace, code folding, and multilevel undo/redo, and handles very large files.

## Use cases
- embed a syntax-highlighted code editor in a .NET winforms app
- build a custom text editor with syntax highlighting in C#
- display and edit very large text files in .NET
- add find/replace and code folding to a .NET textbox
- colorize text based on regular expressions in a .NET control

## When to choose
- you need a fast, embeddable syntax-highlighting editor control for .NET desktop apps
- you want regex-driven custom highlighting rules
- you must handle large files in an editor component

## When to avoid
- you need a cross-platform editor outside Windows/.NET
- you want a full standalone IDE rather than an embeddable component
- you need a web-based editor
