Enterprise services in Windows Server 2008?

[JDeats]

It's been a few years since I worked with transaction based
components, last time I was involved in an enterprise project
requiring transactions my .NET .DLLs were dervived from
ServicedComponent and had to be registered with Microsoft Transaction
Server (COM+ Manager) through COM proxies.

How have things changed in Windows Server 2008?

If the answer is too long for a post, if someone has a good hyperlink
reference that would be unappreciated as well.

The short answer is:
The current microsoft technology of choice to use is WCF:

Windows Server 2008 with IIS 7 now supports hosting WCF Services in WAS
(Supports other protocols besides http(s))
