I have made a fork of the AnkhSVN project and published a version on Visual Studio Marketplace as AnkhSVN2019.
This version targets only Visual Studio 2019.
The page on the Visual Studio Marketplace is here:
https://marketplace.visualstudio.com/items?itemName=PhilJollans.AnkhSVN2019
You can also find it by searching the Visual Studio Marketplace in Visual Studio.
The project is on GitHub here:
https://github.com/PhilJollans/AnkhSVN2019
As far as I can tell it is working correctly, but that is based on a small number of systems, and I only use a subset of the features.
Support for Visual Studio 2022
My fork of AnkhSVN does not support Visual Studio 2022, but there is a version in the GitHub repository from the original developers of AnkhSVN.
As of 4-December-2021, this version is not available in the Visual Studio Marketplace, but you can download the package from the releases page on GitHub.
As of 4-December-2021, the download link for the current version is
https://github.com/AmpScm/AnkhSVN/releases/download/v2.9.87/Ankh-VSIX-2022.zip,
but there may now be a newer version.
