Status/plan of pythonnet for Python 3.9 support #1262

Python 3.9 is not supported, yet. I have opened #1264 to see whether the tests pass, but neither Travis nor Appveyor has Python 3.9 available at this time. Once that is the case, we'll look into it for master. If the changes required are trivial, I'll backport them to the 2.5 branch.

Ok, thanks for the update!

Travis and Appveyor have 3.9 now.

Looks like this can be closed. Looking forward for a new release of pythonnet with support for Python 3.9, thanks!

Is pythonnet available for 3.9.x now? If yes, does it support 3.9.5?
m-rossi commented on May 11, 2021
Officially not, see #1389 for example.

When can we expect an official release of pythonnet available for Python 3.9.0? None of the solutions provided is working on my Windows 10.

Hi @Sshankar7, Please try 2.5.2.0. I tried along with Python 3.9.5 and it's working.

It's November 2021 and the pythonnet library still does not officially support 3.9 yet despite a commit in October that mentioned 3.10 compatibility... does this issue need to be reopened?

Not yet. A pip install still errors out on Python 3.9.6.
Richard944 commented on Dec 9, 2021
This looks like it needs to be reopened because there is no 3.9 support on pypi.org.
In an unsecure workaround people are using it by downloading a wheel file from an .edu site:

There's now 3.0.0a1 package available with 3.9 support
Richard944 commented on Dec 17, 2021
Not really? Looking on pypi.org it's the same 2.5.2 from Feb 5, 2021 (https://pypi.org/project/pythonnet/). Is there some disconnect in how this package gets released?

@Richard944 https://pypi.org/project/pythonnet/#history
BTW, @filmor , there's no alpha for 3.10. Do we have anything blocking it?

You can install pre releases with
See https://pip.pypa.io/en/stable/cli/pip_install/#pre-release-versions

"PRE-RELEASE" Thanks!
filmor commented on Dec 17, 2021
No, this is just a mistake in the metadata. I'll fix it tomorrow.

I'm finding that pythonnet 3.0.0a1 works and pythonnet 3.0.0a2 does not work. There must be some difference. I am running a 3.9.6 python virtual environment.
With both versions I see the dll in site-packages\pythonnet\runtime.
...venv_amd64_3.9.6\lib\site-packages\pythonnet_init_.py:44: in load
raise RuntimeError("Failed to initialize Python.Runtime.dll")
E RuntimeError: Failed to initialize Python.Runtime.dll
I'm ok using 3.0.0a1 but I wanted to share what I saw.

@Richard944 I recommend opening a separate issue for this error.

The pre-release version can now also be installed via conda by executing
