Convention: Spawn New

In certain cases a service can or should be configured before use.

Some examples:

  1. The ToSic.Eav.Services.IDataFactory can be configured to specify what data type it should produce
  2. The ToSic.Sxc.Services.IDataService can be configured with an AppIdentity so that created sources will be tied to that App

Since we use Dependency Injection we can't just add a parameter to the constructor. Since we want our APIs to be immutable, we can't just run an Init or Setup method.

So the solution is to give each of these services the ability to spawn a new service with the new configuration.

This is usually done using a New(...) method which specifies the configuration which the new service should have.
