This video covers support for dependency injection in ASP.NET Core and minimal APIs. Dependencies are objects that other objects can depend on; in ASP.NET Core, these are typically implemented as C# classes and interfaces. Dependencies are stored in the service container. Injection is the process by which a referenced dependency is resolved from the service container. This can happen when a class is constructed or in route handlers. In this video, Safia will utilize dependency injection to centralize the logic associated with the task management into a concrete implementation of ITaskService.
