I want to create my first extension for VS 2022, but I don’t fully understand what is what.

Judging by the name, the extension expands the functionality of the VS 2022 program. I did not find a clear guide on creating project templates and how to add them to your extension (it should be in a ZIP file). As for the project template itself, it’s even worse than it actually is.

The fact is that the project template itself will not create any files when created (the project itself will work directly with the files to which they relate; in the Solution Explorer, you want “Properties” to be created, as in other templates, this is something like settings project). But then it’s not clear whether “Properties” are settings for the project itself or are they extensions themselves
