IoC Lifecycle in C#: Complete Guide

In C#, IOC containers manage the lifecycle of objects, determining when they are created and destroyed. Common lifecycles include:

1. Every time an object is requested from the IOC container, a new instance is created, and each instance is independent. It is suitable for situations where object states do not need to be shared.
2. Singleton: The IOC container will only create one instance and share this instance throughout the lifetime of the entire application, suitable for situations where object state needs to be shared.
3. Scoped: Sharing object instances within the same scope but keeping them independent in different scopes. This is useful for situations where object instances need to be shared within a specific scope, such as in ASP.NET Core where each HTTP request has its own isolated scope.

Apart from the common lifecycle options mentioned above, you can also define more flexible object lifecycle rules by using a custom lifecycle manager. When using an IOC container, it is important to select the appropriate lifecycle rules for your business needs to avoid unnecessary resource waste or confusion in object states.
