ASP.NET Core dependency injection service lifetimes

When using dependency injection, there are three service lifetimes that can be used:

• Singleton
• Scoped
• Transient

Your job is to match each service lifetime with one of the definitions below:

• The lifetime is initalised when a HTTP request has been made and is disposed of when the HTTP response has been sent. It can also be defined explicitly.
• The lifetime is initalised every time a service is injected.
• The lifetime will last for the lifetime of the application.
