IoC, Dll References, and Assembly Scanning

Question

Although this question is related to StructureMap, my general question is:

When wiring up components with an IoC container in code (a

I finally got this sorted out. It looks like this:

IoC Uml http://img396.imageshack.us/img396/1343/iocuml.jpg

with the assemblies

• Core.exe
• PersonBase.dll (referenced compile time by Core.exe)
• Bob.dll (loaded up run time via StructureMap Scan)
• Betty.dll (loaded up run time via StructureMap Scan)

To get it with StructureMap, I needed a custom "ITypeScanner" to support scanning for assemblies:

public class MyScanner : ITypeScanner {
  public void Process(Type type, PluginGraph graph) {

    if(type.BaseType == null) return;

    if(type.BaseType.Equals(typeof(PersonBase))) {
      graph.Configure(x => 
        x.ForRequestedType()
        .TheDefault.Is.OfConcreteType(type));
    }
  }
} 

So my main code looks like:

ObjectFactory.Configure(x => x.Scan (
  scan =>
  {
    scan.AssembliesFromPath(Environment.CurrentDirectory 
    /*, filter=>filter.You.Could.Filter.Here*/);

    //scan.WithDefaultConventions(); //doesn't do it

    scan.With();
  }
));

ObjectFactory.GetAllInstances()
 .ToList()
  .ForEach(p => 
  { Console.WriteLine(p.FirstName); } );
