Possible invalid lifetime for EmailService

[phorks]

According to the course lectures, the reasoning behind registering the email service as transient is to prevent the service from being created for every request and to use a single instance throughout the application lifetime. This means that the service must be registered as singleton since transient means a new instance will be created EVERY TIME the service is requested from the dependency injection framework.

so what is your recommendation ? should I use singleton on there ?

[phorks]

Yes. If you intend to have a single instance of EmailService for all requests, singleton is the appropriate lifetime.
