DI in ASP.NET Core 6

.NET 6 comes with a built-in IoC container framework, which simplifies DI. This comes with the Microsoft.Extensions.DependencyInjection NuGet package and the ASP.NET Core 6 framework itself relies heavily on this. To support DI, a container needs to support three basic actions on objects/services, as outlined here:

• Registering: The container should have provisions to register dependencies. This will help to map the correct type to a class so that it can create the right dependency instance.
• Resolving: The container should resolve dependencies by creating a dependency object and injecting it into the dependent instance. IoC container manages the creation of registered objects by passing in all the required dependencies.
• Disposing: The container is responsible for managing the lifetime of dependencies created through it.

In .NET 6, the following terms are used:

• Service: Refers to a dependency managed by a container
• Framework services...
