AutoWiring with StructureMap, Constructor Injection...

Question

Hi, I'm new to structuremap. :))

I have a class which implements IPresenter :

public class SoldierPresenter : IPresenter
{
...
public SolierPresenter(ISoldierView soldierView)
{

}
...
}

When I call :

var presenters = ObjectFactory.GetAllInstances<IPresenter>();

I get zero instances... what am i missing?!

Here is the configuration code for the container:

  Scan(
            scanner =>
                {
                    scanner.AssemblyContainingType(typeof(IShell));
                    scanner.WithDefaultConventions();

                    scanner.TheCallingAssembly();
                    scanner.AddAllTypesOf<IPresenter>();

                    scanner.WithDefaultConventions();
                });

Thanks in advance, Erik.

Container.WhatDoIHave(); Shows the following:

Your code sample does not provide enough information. Are you configuring the container owned by ObjectFactory, or are you creating your own instance of Container? ObjectFactory can only access its own Container.

You are trying to call GetAllInstances on ObjectFactory, but you call WhatDoIHave on Container. It is not clear which container you are configuring with the "Scan" statement you included.

Using the code you provided (and assuming use of ObjectFactory throughout), I was not able to reproduce your issue. Make sure you are consistently using the same container.

If that doesn't solve your problem, you might consider posting to the StructureMap mailing list, where it will get a lot more attention from StructureMap users.
