## What it is
CodeFormatter is a command-line tool that uses Roslyn to automatically rewrite C# source code to follow the .NET team's coding style rules. The repository is archived and replaced by dotnet/format.

## Use cases
- automatically format c# code to match dotnet coding style
- rewrite source files using roslyn
- convert mstest tests to xunit
- enforce copyright headers on c# files

## When to choose
- you need to apply the .NET team's legacy coding style to C# projects
- you want to bulk-convert MSTest tests to xUnit

## When to avoid
- you want a maintained formatter - use dotnet/format instead
- you work on non-Windows platforms or modern .NET SDK projects
- you need configurable formatting rules
