## What it is
RoslynQuoter is a C# tool that takes C# source code and generates the Roslyn SyntaxFactory API calls needed to construct its syntax tree. It is available as a NuGet library, a web app, and a LINQPad-friendly tool.

## Use cases
- generate roslyn syntax factory calls for c# code
- learn how to build c# syntax trees with roslyn
- convert c# source code to roslyn api calls
- create roslyn syntax tree programmatically for a snippet
- understand roslyn syntax tree structure of c# code

## When to choose
- you are writing Roslyn analyzers or code generators and need to construct syntax trees programmatically
- you want to learn the Roslyn SyntaxFactory API by example
- you need to convert existing C# code into syntax-construction API calls

## When to avoid
- you need semantic analysis or compilation, not syntax tree construction
- you work with languages other than C#
- you need a general-purpose C# formatter or refactoring tool
