Microsoft’s shift to a new .NET is nearly complete. .NET Core 3.0 is here, and it’s the foundation for next year’s big bang release of .NET 5.0. That’s when .NET Core becomes the main development branch for all of .NET, and the old .NET Framework slides off into a well-deserved retirement and a very long support lifecycle.
That doesn’t mean all your existing .NET code will run on .NET 5.0. To be honest, odds are it won’t. This is the new Microsoft, not the old, and keeping legacy code alive is no longer a priority.
