I am attempting to use the following Generic Repository Interface for DI and constructor injection:

```
public interface IRepository<TEntity> : IDisposable where TEntity : class

```

The problem is in order to define an instance of the Interface, I must provide the class type like this:

```
private IRepository<Person> _personRepository;

```

The issue with this is if I'm using DI (and I'm using Unity for IoC framework), then I have to define multiple instances in my constructor to get all repository interfaces I need to work with like this:

```
public MyClass(IRepository<Person> personRepository,
               IRepository<Orders> ordersRepository,
               IRepository<Items> itemsRepository,
               IRepository<Locations> locationsRepository)
{
  _personRepository = personRepository;
  _OrdersRepository = ordersRepository; 
  _itemsRepository = itemsRepository;
  _locationsRepository = locationsRepository;
}

```

Questions:

1. Is this OK?
2. If not where am I lost on this concept?
3. Even if this is proper, what's the point of Unity to register Interface to concrete type? I've already done it because the generic repository forced me on declaration.

Please help clear this up for me, and I appreciate all your help!
