Explore the theory behind dependency inversion, dependency injection, and IOC containers, clarifying how abstractions and details relate, and how inversion of control enables these patterns and frameworks in applications.
Explain how the dependency injection container manages lifetimes—transient, scoped, and singleton—and illustrate with a GUID service and startup registrations to show creation and reuse behavior.
Transient services are recreated per http request, not necessarily thread-safe, avoiding sharing but increasing memory usage; use them when unsure which lifetime fits best, as shown in the middleware example.
Register open generic services in the dependency injection container using a generic repository pattern to enable CRUD across entities, illustrated with the order microservice, IRepository, and OrderRepository.
Register application and infrastructure services with extension methods on IServiceCollection to simplify ConfigureServices, embrace the fluent design pattern, and keep startup clean within clean code architecture.
Explore constructor injection in ASP.NET Core, learn rules for public constructors, and how ActivatorUtilities and IServiceProvider resolve constructors for controllers, middleware, and other components.
Discover view injection in ASP.NET Core by injecting configuration data and services into Razor views with the inject keyword, and rendering UI elements based on available settings and Guid service.
Concepts such as Dependency Inversion, Inversion Of Control, IOC Container, Dependency Injection are very important but confusing concepts while developing code in today's world. In this course, we will define these concepts. We will describe the Microsoft Dependency Injection Container, which comes as Fundementals in ASP NET CORE Framework and forms the basis of almost all components, with all its features. In this way, you will be able to increase the quality of your applications by developing more efficient, sustainable, testable and lavishly coupled applications by using this information while developing code in daily life.
What is Dependency Inversion Principle?
What is Inversion Of Control Principle (IOC)?
What is Dependency Injection Design Pattern?
Why do we use Dependency Injection Container?
What are the benefits of Dependency Injection Container?
What architectural problems will we encounter if we do not use a Dependency Injection Container? What are the disadvantages of these problems? How does the Dependency Injection Container solve these problems?
What is Dependency? How do we detect dependencies?
What are Service Lifetimes? How do we manage relationships between each other?
When to use Transient, Scoped, Singleton Lifetimes?
While answering questions such as;
We will learn the end-to-end use of Microsoft Dependency Injection Container by making examples about Microsoft Dependency Injection Extension methods and their uses, and solutions to more complex problems through the Microservice architecture training project. We will also have a few examples on how you can develop Clean Code using Dependency Injection.
Our expectation is not that you develop in parallel while following the training, but that you understand the scenarios, concepts and what we do and why we do it. We shared all the projects used in education as open source code. In this way, you can test the codes described in the training yourself and reinforce what you learned in the training.
