 # Life Cycles
 
+In ASP.NET, dependency injection (DI) lifecycles determine the lifetime of objects that are resolved through the DI container. There are several predefined lifecycle options in the `Microsoft.Extensions.DependencyInjection` library, including:
 
+- **Transient:** A new instance of the object is created every time it is requested.
+- **Scoped:** A new instance of the object is created for each request within the same scope.
+- **Singleton:** A single instance of the object is created and shared across the entire application.
+
+Additionally, you can also create a custom lifecycle by implementing the `Microsoft.Extensions.DependencyInjection.IServiceScopeFactory` interface
