With .NET 5 things are going back to a "check the version number" naming system though. 5 is greater than .NET Core 3.x, .NET Framework 4.x, and .NET Standard 2.x, you can pretty much forget what Core/Framework/Standard entirely mean as soon as you can upgrade to 5. (And the next version is .NET 6.) It's one version number left now.

(Also, DirectX tried to version number individual components at various points in its history so even DirectX "naming" isn't that straightforward at certain points in time in the past.)
