Auto-register all interfaces with Unity

Question

Using Unity, I'd like to automatically register all interface/class combinations in an assembly based on the following convention:

INameOfObject > NameOfObject

StructureMap does that when the default conventions are enabled.

I wrote the following method for it:

private static IUnityContainer RegisterITypesOf(this IUnityContainer container, string assemblyName)
{
  Assembly.Load(assemblyName)
    .GetTypes()
    .Where(t => t.GetInterfaces().Any(i => i.Name == "I" + t.Name))
    .ForEach(t => container.RegisterType(t.GetInterface("I" + t.Name, false), t));
  return container;
}

My question is:

• is there a built-in function that does the same?
• if not, can my code be improved performance wise?

Answer 1

Unity 3.5.140.0 has built in functionality to register interfaces with similar names as the class that uses it.

public static void RegisterTypes(IUnityContainer container)
{
    container.RegisterTypes(
    AllClasses.FromLoadedAssemblies(),
    WithMappings.FromMatchingInterface,
    WithName.Default);
}

Answer 2

I wanted the same as you; convention based configuration ala Structuremap, and went ahead and created a library for it. You can download it on NuGet, and read some documentation on my github page

Hope this helps!

Unity does not have support for conventions. But the TecX project on codeplex contains an enhanced configuration engine for Unity that is based on StructureMap's configuration.
