Visual Studio Code has absolutely nothing to do with Visual Studio. Both are used to edit code.

.NET Core is a ground up rewrite of .NET and was released alongside the original .NET, which was renamed .NET Framework to distinguish it. Both can be equally considered to be "frameworks" and "core" to things. They then renamed .NET Core to .NET.

And there's the name .NET itself, which has never made an iota of sense, and the obsession they had with sticking .NET on the end of every product name for a while.

I don't know how they named these things, but I like to imagine they have a department dedicated to it that is filled with wild eyed lunatics who want to see the world burn, or at least mill about in confusion.

Java and Javascript would like to have a chat :)

But Copilot is another Microsoft monstrosity. There's the M365 Copilot, which is different from Github Copilot which is different from the CLI Copilot which is a bit different from the VSCode Copilot. I think I might have missed a few copilots?

user: How do I shutdown this computer?

tech: First, click on the "Start" button...

user: No! I want to shut it down

I remember they prepended the word “Microsoft” to official names of all their software.
