## What it is
ClojureCLR is a native implementation of the Clojure programming language on the .NET Common Language Runtime, written in C# and Clojure. It can run standalone or be embedded as a library in .NET applications, aiming for feature parity with the JVM implementation.

## Use cases
- write clojure code on the .net platform
- embed a lisp scripting language in a c# application
- run clojure without the jvm
- use clojure with .net libraries
- port existing clojure projects to clr

## When to choose
- you want Clojure semantics but must target .NET/CLR
- you need to interoperate with C#/.NET libraries from Clojure
- you want to embed a dynamic functional language in a .NET app

## When to avoid
- you only need standard JVM Clojure - use the official JVM implementation
- you need a large ecosystem of CLR-specific Clojure libraries - ports are limited
- you require guaranteed long-term support - the project has no explicit license file and a small team

## Facets

- maturity: active
- function: interpreter, programming-language
- domain: programming-languages, cross-platform, developer-tools
