CSnakes - a tool for embedding Python code into .NET projects
CSnakes is a .NET Source Generator and Runtime that you can use to embed Python code and libraries into your C#.NET Solution at a performant, low-level without the need for REST, HTTP, or Microservices.
Check out the getting started guide or check out the demo solution to see more.
Features
- Supports .NET 8 and 9
- Supports Python 3.9-3.13
- Supports Virtual Environments and C-Extensions
- Supports Windows, macOS, and Linux
- Tight integration between NumPy ndarrays and Spans, 2D Spans and TensorSpans (.NET 9)
- 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 CPython 3.13 "free-threading" mode
- Supports nested sequence and mapping types (
tuple
,dict
,list
) - Supports default values
Benefits
- Uses native Python type hinting standards to produce clean, readable C# code with minimal boiler plate!
- Integration between .NET and Python is done at the C-API, meaning strong compatibility between Python versions 3.8-3.13 and .NET 8-9.
- Integration is low-level and high-performance.
- CSnakes uses the CPython C-API and is compatible with all Python extensions.
- Invocation of Python code and libraries is in the same process as .NET
Example
CSnakes will generate a C#.NET class for any Python file in a project that is tagged as CSharp Analyzer Additional File (see Getting Started). All functions in that class with type annotations will be reflected to callable C# methods and an environment builder added to that module.
