Confused about target frameworks

Hello,

I’ve just built my firsty plug-in for Rhino 8 following the official guide: Rhino - Your First Plugin (Windows)

I’m confused about the target frameworks. In the project properties I see that the target frameworks are “net7.0-windows;net7.0;net48”. When I build I get 3 different executables, one for each framework. Which one should I load in Rhino?
