(CPython) <==> (.NET) direct interop via embedded CLR (.pyd) through Boost.Python

PyDotnet only works on Windows due to integration with Microsoft .NET environment (.NetCore C++/CLI for Linux and MacOS - Is not supported)

Works natively on Windows 64-Bit (x86), and also on Windows on ARM64 in AMD64 emulation mode.

Works well on Windows on ARM64 on Apple Silicon: Parallels® Desktop 18 for Mac

Haven't tested, but this might work: Windows-Docker-Machine

Import .NET seamless integration for CPython shell

Import .NET namespace

import System

Import type from .NET namespace

from System.Collections.Generic import List

Create an instance of .NET type. This shows also how to specialize .NET generic type

lst = List[Int32]()

Call instance method of .NET type. This also converts Python int into .NET Int32

lst.Add(1)
lst.Add(2)
lst.Add(3)

Call instance method of .NET type. This also converts Python list into .NET IEnumerable

lst.AddRange([4,5,6])

Call instance method of .NET type. Here Python lambda gets converted into .NET Predicate. The invocation jumps from Python into .NET CLR and calls back to Python lambda

lst.FindIndex(lambda x: x > 3)

pip install dotnet
