DI in Blazor focuses on implementing Dependency Injection to build modular, maintainable, and scalable web applications. It enables developers to manage services and application components efficiently by reducing tight coupling between objects. This training explains how Dependency Injection works in Blazor applications using built-in .NET service containers. It also covers service lifetimes such as Singleton, Scoped, and Transient, along with constructor injection and service registration techniques. You will learn how organizations use DI to improve code reusability, testing, and application architecture in Blazor projects. The course also highlights best practices for managing dependencies and building clean enterprise-grade applications.
