TWIL vol.3 (.NET Framework limitations, VS2022 and legacy apps, and the default keyword) New year, new discoveries... WinForms can be upgraded to .NET; default vs null in C#; VS 2022 won't show the Form designer in legacy apps

What we get is white screens of brokenness whenever we try to open a Form in the designer. But why?
