Re: Web Forms needs to be moved forward onto .NET Core
"Isn't that what .NET 5.0 is?"
No it isn't. .NET 5 is .NET Core. It was going to be .NET Core 4. But, Microsoft decided to rename it so not to confuse it with .NET Framework 4.x.
But it will confuse the hell out of developers when their Framework project is moved to .NET 5 and there are a ton of breaking changes.
