Check [NotNull] in the game studio about xenko HOT 2 OPEN

That is not the purpose of NotNull. It is a design-time only attribute used to let ReSharper do a static analysis to detect wrong usages of nullability.

@Kryptos-FR Oh, I assumed that it didn't have anything to do with that [NotNull] attribute, since it's defined inside SiliconStudio.Core.Annotations.

Well, what would be an alternative to achieve what I want to achieve? It's not that uncommon that a component needs a reference to another component to work properly.

Checking it in code would require me to write a lot of extra code that I would prefer to avoid writing. Also, it would be a runtime check rather than a game-studio-time check.

Dependency injection would be one alternative that I can think of right now.
