Usage of deprecated Python functions slated for removal in Python 3.15 #2592
Description
Hi, I'm a CPython core developer and we are currently working on the next alpha, namely Python 3.15. In Python 3.15, we are removing a bunch of deprecated functions (see python/cpython#133661 and https://github.com/python/cpython/pull/133661/files#diff-bd7a9c5b54eeb2b40e6db5e48e8d79d309d8738e776a40918773c6840189edf9).
We found the following references in this project, but as I never coded in .NET, I don't know how to change them:

The respective replacements are
PyConfig_Getwith the right parameters from Python 3.14 onwards, right? I can have a look into implementing these along with 3.14 support.Thank you very much for the heads up!

Yes indeed! don't forget to hold the GIL though. If there are issues, please open a ticket on python/cpython.
