You have Fine Code Coverage working with VS 2022, you can access to it here
https://github.com/FortuneN/FineCodeCoverage/releases and click on the 2022 file.
After that, it´s just a plugin that you install on your computer and it´s available to every single project without the need to add it project by project.
Update:
Now it’s available directly from the marketplace, so you can install it from the Extensions Manager or you can download it from marketplace (https://marketplace.visualstudio.com/items?itemName=FortuneNgwenya.FineCodeCoverage2022) and execute it on your computer.
