It's even worse, since they dropped the core now and just call it .NET. So searching has become even more of a pain. It's also pretty much a mess, because many things were different between the versions.

So let's say you google how to do something and the result could be:

  - .NET Framework
  - .NET core 1
  - .NET core 2
  - .NET core 2.1
  - .NET core 3
  - .NET 5+

Many times there will be no clear indication what version the result was built on.

On stackoverflow, answers sometimes include all versions varieties.
