UniTaskVoid Start() shows incorrect signature warning

[KichangKim]

When using UniTaskVoid for MonoBehaviour.Start(), VisualStudio shows incorrect signature warning like this:

Warning	UNT0006	The Unity message 'Start' has an incorrect signature.

I don't think it's a bug. The return value should be void.

Not related, but I saw your posts on the Unity forums about deadlocks when using Addressables. I'm seeing the same bug in my game, did you figure it out eventually?

This is because Unity does not officially support async of Start.
Unity calls Start dynamically and does not care about the return value.

If you are using UniTask and want Start to be async, use UniTaskVoid. (and ignore the warning).
If you don't do that, call FooAsync().Forget() in void Start.
