What is the best practice to implement multi tenancy in ASP.NET MVC using Castle Windsor?

I have a service with two different implementations and I would like to inject into the controllers constructor, depends on a criteria (at the moment the criteria is a simple value stored in session).

Here is what I got now...

Service interface:

public interface IService
{
    string GetSampleText();
}

Implementation #1:

public class FirstService : IService
{
    string GetSampleText()
    {
        return "First Service";
    }
}

Implementation #2:

public class SecondService : IService
{
    string GetSampleText()
    {
        return "Second Service";
    }
}

Registration in a Windsor installer class:

container.Register(AllTypes
  .FromAssemblyInDirectory(new AssemblyFilter(HttpRuntime.BinDirectory))
  .BasedOn<IService>()
  .WithService.FromInterface()
  .Configure(c => c.LifeStyle.Transient));

container.Kernel.AddHandlerSelector(new ServiceHandlerSelector());

I have implemented an IHandlerSelector:

public class ServiceHandlerSelector : IHandlerSelector { ... }

In the HasOpinionAbout method of this IHandlerSelector implementation I can decide which handler will be selected in the SelectHandler method (depends on the value from session).

Then the constructor injection is working fine on the controllers:

public MyController(IService service) { ... }

So I got a working solution, but I am not sure if it is the best way to do this.

Opinions? Suggestions?

Many thanks.

You're on the right track with handler selectors. Here are some good articles on using them for multi-tenancy, you can use them for reference:
