castle: register interface proxies by convention

Question

I want to register multiple components implementing the dictionary adapter, but the AllTypes.From.. only picks class-types. I want to do something like this:

        container.Register(AllTypes.FromAssemblyContaining<IFooSettings>()
            .Where(type => type.IsInterface)
            .Configure(component =>
                component.UsingFactoryMethod((kernel, model, creationContext) => new DictionaryAdapterFactory().GetAdapter(creationContext.RequestedType, ConfigurationManager.AppSettings))));

Now I can't seem to be able to create my own version of "AllTypes" since the FromTypesDescriptor ctor is internal. Any ideas how I can accomplish this?

Answer 1

This now works in Castle 3.3.0:

var dictionaryAdapterFactory = new DictionaryAdapterFactory();

container.Register(
        Types.FromThisAssembly().Where(t => t.Name.EndsWith("Settings") && t.IsInterface)
            .Configure(component => component.UsingFactoryMethod((kernel, model, creationContext) => dictionaryAdapterFactory.GetAdapter(creationContext.RequestedType, ConfigurationManager.AppSettings))));

You have to use "Types" which also picks up interfaces

Answer 2

I do something like this

    container.Register(
        AllTypes
            .FromThisAssembly()
            .Pick()
            .WithService.DefaultInterface()
            .Configure(r => r.LifeStyle.Transient));

This registers components based on a matching interface and class name.

So if I ask Castle for an interface called IFooSettings then Castle will by default return the class FooSettings.

There are a series of rules you can use for registration and you can see them here. It's does not recommend using the Factory method you are using in your example.
