What is service lifetimes in ASP.NET Core?

Question

Amit Mohanty · Answer

ASP.net core allows us to specify the lifetime for registered services. The service instance gets disposed of automatically based on a specified life-time. So we do not care about the cleaning these dependencies, it will take care of the ASP.net core framework. There are three types of life-times. 1 - Transient 2 - Scoped 3 - Singleton For more details check the below links. https://www.dotnettricks.com/learn/dependencyinjection/implementation-asp-net-core-mvc https://code-maze.com/dependency-injection-lifetimes-aspnet-core/

There are three lifetimes that can be used with Microsoft Dependency Injection Container, they are: Transient — Services are created each time they are requested. It gets a new instance of the injected object, on each request of this object. For each time you inject this object is injected in the class, it will create a new instance. Scoped — Services are created on each request (once per request). This is most recommended for WEB applications. So for example, if during a request you use the same dependency injection, in many places, you will use the same instance of that object, it will make reference to the same memory allocation. Singleton — Services are created once for the lifetime of the application. It uses the same instance for the whole application

Service lifetimes available in .NET Core: Transient – created each time they’re requested from the service container Scoped – created once per client request and is reused within that request Singleton – created only once and is reused across the application’s lifetime We can register these services with the AddTransient(), AddScoped() and AddSingleton() methods respectively.
