This package is a tool to easily install NuGet packages and load the compiled .NET DLL's into python. It uses Pythonnet in the background to load and run the DLL's.
In order to use this package you need to have .NET installed and added to your PATH, verify with:
dotnet --versionFirst, install the package:
pip install dotnetinteroptAdd it to the build backend dependencies:
[build-system]
requires = [..., "dotnetinteropt"]And append the following to your pyproject.toml file:
[tool.dotnetinterop]
# OPTIONAL:
# NuGet dependencies used in the project. Can be omitted when
# no dependencies are needed:
dependencies = [
[
"Newtonsoft.Json", # Replace with the actual NuGet package name
"13.0.3", # Replace with the actual NuGet package version
],
# Add more dependencies here
]
# name of the package to install it in.
# Replace with the actual package name (needed for multi-package projects)
# Otherwise the package name is inferred from the package name in the pyproject.toml:
package = "dotnetinteropt"
# path to where the DLL files should be copied to (relative to package):
path = "_dotnetinteropt" # Default
# Compiled in release or debug mode:
release = true # Default
[tool.setuptools.package-data]
"*" = ["*.dll"] # include all DLL files from all packagesCreate a setup.py file in the root of your project:
from setuptools import setup
from dotnetinteropt.backend import install_nugets
if __name__ == "__main__":
install_nugets() # Has to be before setup such that it then can include the DLL's
setup()In your python code you can now load the DLL's:
from dotnetinteropt import load
# Load the DLL's
load("dotnetinteropt_examples") # Change to the package where to find the DLL's
# Now you can import the symbols from the DLL's
from Newtonsoft.Json import Formatting
from Newtonsoft.Json import JsonConvert
from System import *
from System.Collections.Generic import DictionaryTo generate the examples run:
make examplesThen run the examples with:
python3 src/dotnetinteropt_examples/hello_dotnet.py
python3 src/dotnetinteropt_examples/json_dotnet.pyAlso, check the pyproject.toml file for the example configuration.
