CSnakes - a tool for embedding Python into .NET projects

Warning

This project is in prototype stage and the API is subject to change.

Documentation

CSnakes is a .NET Source Generator and Runtime that you can use to embed Python code and libraries into your .NET Solution without the need for REST, HTTP, or Microservices.

Features

• .NET Standard 2.0 (.NET 6-8)
• Supports Python 3.9-3.13
• Supports Virtual Environments and C-Extensions
• Supports Windows, macOS, and Linux
• Uses Python's C-API for fast invocation of Python code directly in the .NET process
• Uses Python type hinting to generate function signatures with .NET native types
• Supports nested sequence and mapping types (tuple, dict, list)
• Supports default values

Examples

Given the following Python file called example.py

def hello_world(name: str, age: int) -> str:
  return f"Hello {name}, you must be {age} years old!"

CSnakes will generate a static .NET class called Example with the function:

public class Example {
  public static string HelloWorld(string name, long age) {
    ...
  }
}

When called, HelloWorld() will invoke the Python function from example.py using Python's C-API and return native .NET types.
