Is there a way to define a class property with some sort of "onready" functionality, similar to how it's done in gdscript? Could it be something similar to how exports are defined? ( I haven't been able to see any mention of this anywhere.

Something like this maybe?

public class Game : Node
    public Sprite sprite = GetNode("Sprite");

just do it in the _Ready() function?

public Sprite sprite;
public override void _Ready()
    sprite = GetNode<Sprite>("Sprite");

Thanks for the response. I'm aware of that approach, but was hoping there was something a little more terse available.

They could build a Attribute system to do what you want,

The problem is it's a lot of work, and pretty bad performance, and (arguably) makes your code harder to read. So very much not surprised this isn't supported.

thanks I came here looking for onready var timer: Timer = $Timer alternative in C#.

There's a recent proposal to add a C# version of onready to Godot proper:

In the meantime, I wrote an open-source C# Source Generator that can generate the boilerplate, to make it more terse:

It generates _Ready() based on [OnReadyGet("Sprite")] private Sprite _sprite;. (It also optionally exports a NodePath property so you can change "Sprite" for specific nodes in the editor.) It doesn't use reflection, so it doesn't have that performance cost.
