Where are TinyCLR project template files installed?

I’m trying to create some custom project templates for TinyCLR. So far, I can’t get Visual Studio 2026 to recognize them when I install them to the same place I normally put .Net templates.

So, I’d like to compare my templates to those that are part of the TinyCLR extension. But I can’t find the latter. Where does the extension install its project templates?
