Modernizing a codebase for C# 9

There are lots of cases that you can improve. The examples use nullable reference types, but only the WhenNotNull example requires it.

Use the property pattern to replace IsNullorEmpty

Consider adopting the new property pattern, wherever you use IsNullOrEmpty.

string? hello = "hello world";

; This is a complete solution to map the CapsLock key to Control and Escape without losing the ability to toggle CapsLock
; We use two tools here - any remapping software to map CapsLock to LControl and AutoHotkey to execute the following script
; This has been tested with MapKeyboard (by Inchwest)

; This will allow you to
;  * Use CapsLock as Escape if it's the only key that is pressed and released within 300ms (this can be changed below)
;  * Use CapsLock as LControl when used in conjunction with some other key or if it's held longer than 300ms
;  * Toggle CapsLock by pressing LControl/CapsLock + RControl
