I’ve been actively using .Net since 2008. Sure it changes slowly with the biggest change with .Net Core and ASP.Net Core and EF Core. But it didn’t take that long to learn the differences.

Then there's Blazor, there's MAUI, there are changes in C# itself and lots of new libraries.

Changing - do I have to learn something new to do the same thing today as I did yesterday - is different than adding new capabilities.
