Embracing Change: My Journey from Autofac to .NET Core’s Built-In DI
As a senior developer working with .NET, I’ve navigated through various architectural paradigms. One significant turning point was moving from a monolithic .NET Framework web application to a more modern .NET Core approach, primarily due to the differences in handling Dependency Injection (DI). I am sharing my experience here in this blog and giving step-by-step implementation and the end testing your understanding of DI in .NET core. So read until the end and take a quiz to test yourselves.
The Monolithic Challenge: Our legacy application was a tightly-coupled monolith. Changing one component often led to a cascade of modifications. Testing was cumbersome, and deployment, a nightmare.
In our .NET Framework app, a change in the data access layer required alterations across multiple service layers, due to tight coupling. For instance, modifying the UserRepository
impacted the UserService
, which in turn affected the UserController
.
Discovering Autofac: We first adopted Autofac to manage our dependencies better. Autofac’s flexibility was a revelation, enabling more manageable, testable, and modular code. However, it was an external dependency that we had to manage.
Implementing Autofac allowed us to define clear interfaces and their implementations. For…
