singleTone vs Transient vs Scoped and HostedService
Transient — Services are created each time they are requested. It gets a new instance of the injected object, on each request of this object. For each time you inject this object is injected in the class, it will create a new instance.
Scoped — Services are created on each request (once per request). This is most recommended for WEB applications. So for example, if during a request you use the same dependency injection, in many places, you will use the same instance of that object, it will make reference to the same memory allocation.
Singleton — Services are created once for the lifetime of the application. It uses the same instance for the whole application.
transient > scoped > singleton
for using 'scoped' in 'singleton' we can use 'serviceprovider'
