Dependency Injection Lifetimes in .Net Core

There are three lifetimes available with the Microsoft Dependency Injection container: transient, singleton, and scoped. The lifetime of the service is specified when registering the service in the container. As we will see shortly, because a service can be used in different places in the application, the service lifetime will affect whether the same instance of the service is consumed across the application, thus affecting the output.

1- Singleton Lifetime:

One instance, lasting throughout the application. Ensures a consistent, shared resource for the entire program. Ideal for stateless services and globally accessible components.

2- Scoped Lifetime:

Instance tied to a specific operation or request. Perfect for managing resources during an HTTP request. Ensures a clean slate for each request, enhancing isolation.

3- Transient Lifetime:

Fresh instance every time. Ideal for short, stateless operations. Ensures a clean, disposable resource for each injection. Quick and efficient for on-the-fly tasks.

Now, I will show you an example of how these types work.

In summary, mastering ASP.NET Core's dependency injection lifetimes—Singleton, Scoped, and Transient—provides the foundation for building efficient and adaptable applications. Choosing the appropriate lifetime ensures resource optimization, scalability, and streamlined maintenance. Whether aiming for global consistency, request-specific handling, or swift disposability, these lifetimes offer tailored solutions to diverse development challenges. Embracing these nuances is pivotal for crafting resilient software that evolves with changing requirements. ?????
