## What it is
CSnakes is a .NET source generator and runtime library for embedding Python code and libraries directly into C# .NET applications via the CPython C-API. It generates strongly-typed C# wrappers from Python type hints, enabling fast in-process interop without REST or microservices.

## Use cases
- call python code from c#
- embed python in a .net application
- use python libraries like numpy from c#
- interop between dotnet and python without http
- generate c# bindings from python type hints
- run python machine learning models inside a .net app

## When to choose
- you need high-performance, in-process Python/.NET interop without network overhead
- you want strongly-typed C# method signatures generated from Python type annotations
- you need to use Python packages with C extensions (like NumPy) from .NET

## When to avoid
- you need to call .NET code from Python rather than the other way around
- you want a language-agnostic RPC or microservice boundary between Python and .NET
- your Python code must run in a separate process for isolation or stability

## Facets
- artifact type: library
- maturity: active
- function: sdk, parser, developer-tools
- domain: developer-tools, cross-platform, machine-learning
- platform: dotnet, python, windows, cross-platform
- tags: python-interop, csharp-source-generator, cpython-c-api, interop, numpy, macos, linux
