Скачать или смотреть Object Lifetime

This is the last video in DI playlist and it culminates entire concept with Object Lifetime.

Object Lifetime is basically how long would your instances live in memory and since we are creating entire object graph in a single place, we can easily control their lifetime.

We do have 3 lifestyles that form up Object Lifetime:
1. Singleton lifestyle - object is created once and kept in memory forever (similar to singleton pattern, but in a memory-management terms). This object can be shared to unlimited number of consumers
2. Scoped lifestyle - object that's kept longer and can be potentially shared between consumers (we can remove it on demand).
3. Transient lifestyle - new object is created on demand and has a limited lifetime.

Object Lifetime is an important concept since it helps you share stateful components between your classes safely and achieves maximum reusability.

Should you have any questions, leave a comment and I will explain more in detail.

Credits to @Essential Developer for helping me learn all of those concepts in detail. If you are curios into learning from the original author, read the book "Dependency Injection, Patterns, Principles and Practices by Steven van Deursen, Mark Seemann".
