What about impure class properties

“

.NET types have methods, but they can also support other members like events, operators, and properties. Just like methods, these members can alter the internal state of an object, leading to side effects. In this video, I'm looking at properties. In functional programming, properties that introduce side effects are generally discouraged because they violate immutability, predictability, and referential transparency. Simple properties implemented with C#'s auto-properties are typically fine. However, the preferred approach is to make the type immutable. If your type isn't immutable and you write custom code in a properties getter or setter, it's important to check if that code is causing any unintended side effects. Here's an example. I have this class called SimpleColor and it's for creating colors from red, green, and blue values. So here you can see I've got these mutable backing fields via properties. I've got red, green, and blue. I've got a constructor here on line 13 that I use…
