How to organize your dependencies in .NET

In the world of .NET development, it’s a common practice to establish registrations for dependencies, ranging from basic services to third-party components obtained through NuGet packages.

1/ Inline Dependency Registration

Consider a straightforward example of dependency registration. Below is an illustration of how dependencies would be registered in a Program.cs file.

2/ Extension Method Dependency Registration

The previous approach is suitable but becomes less efficient as the number of dependencies increases.

A more effective strategy involves relocating these dependencies into an extension method and then invoking that extension method within the Program file.

Add in Program

3/ Modularized Dependency Registration

I prefer to create distinct extension methods for each concern.

Then, I consolidate the invocation of these methods into a single method, and only this method is called in the Program file.

This ensures a more organized and modular approach to dependency registration.

Add in Program file

This way dependencies becomes :

• More clean

• Easy to manage
