.Net 4.0 Is there a business level "Technology"?

Question

I have a theoretical question about .net structure.

As I see it, Microsoft has provided us with many technologies for different layers.

We have ADO.NET and with an improved Entity Framework for data access.

And ASP.NET for the WEB interface. And even WCF for Facade and SOA.

But what's in the middle of what we have for the business level? Are these just DLL links?

How do we work with the application pool these days? I remember using COM + 10 years ago because IIS was not able to handle the pressure.

Is Spring.Net the best option for injection?

Thanks, Ronny
