When to use TableController <T> and when to use Custom DomainManager

Question

I'm trying to figure out when it makes sense to have my own domain manager. I initially claimed that whenever we had a return type that was not type Tin TableController<T>, we needed to create a new Custom DomainManager.

However, in the app Sport by Xamarin sample, their controller inherits from TableController<Athlete>, but their GET method returnsIQueryable<AthleteDto>

public IQueryable<AthleteDto> GetAllAthletes()
{
     return ...;
}

NOTE: AthleteDtoinherits fromEntityData

If allowed, then why should I have trouble creating a new DomainManager?

I only need to create a new DomainManager if my return value is not inherited from EntityData?

Answer 1

You need to create a new DomainManager for each type of data source that you are connecting to. For example, there is a built-in domain manager for Azure table storage and one for Azure SQL using the Entity Framework.

Your data types must inherit from EntityDataor implement an interface ITableDatain order to use TableController<T>. It does not depend on the question of the domain manager.
