Can't figure out how to get this DI stuff going

Ok, I feel like a total idiot. I have read the docs and still cant get this working with Ninject.

 public class ContextAdapter:IDbSetProvider
{
    private readonly IContextFactory _contextFactory;
    #region Implementation of IDbSetProvider

    public ContextAdapter(IContextFactory contextFactory)
    {
        this._contextFactory = contextFactory;
    }

    public IDbSet<TEntity> CreateDBSet<TEntity&g开发者_如何学编程t;() where TEntity : class
    {
        var context = _contextFactory.Create();
        return context.Set<TEntity>();
    }

    #endregion
}

As you can see I am need to inject the contructor for the class above. Well, it is not going so well. Help!! before I go back to writing perl code. Kidding!! LOl

Thoughts folks?

Your class ContextAdapter does not implement IContextFactory. Do you have a class like class Factory : IContextFactory? That is what you are missing here. Then you can bind it kernel.Bind<IContextFactory>.To<Factory>() and Ninject will create that type for you when you request an object or when it needs to fulfill a contract. I think your confusion comes from the binding syntax. You are, in general, not binding parameters together, you are binding interfaces to concrete implementations. Here is a quick example:

Bind<IEngine>.To<GasEngine>();
Bind<ICar>.To<Sedan>();

class Sedan : ICar
{
    public Sedan(IEngine engine) { }
}

// ...

kernel.Get<ICar>(); // get me a new car

When you ask Ninject for ICar, it will fulfill it with what was bound, Sedan. Sedan requires an IEngine in its constructor, which Ninject will fulfill with GasEngine since that is what was bound.
