Angular Injection Context Explained

Ever wonder what an Angular injection context is? Angular's dependency injection system relies on a runtime context called the injection context. We can only use dependency injection in code that runs in that injection context.

In this video, we explain what an injection context is, examine where the injection context is available, and walk through what happens when you inject a dependency outside of the injection context. We use both constructor-based dependency injection, and the inject function introduced in Angular v16.
