Understanding WCF Communication Options in the .NET Framework 3.5
# Wednesday, December 26, 2007

WCF is an impressive technology. It's not the simplest thing in the world--does anybody really feel at home configuring WCF security today?--but it certainly is simpler than the broad set of things it supplants.

One way to appreciate the value of WCF is to take a look at the range of communication styles it supports, especially in the .NET Framework 3.5. I've written a white paper that's meant to help with this. Called Dealing with Diversity: Understanding WCF Communication Options in the .NET Framework 3.5, the paper walks through the variety of approaches that are now supported. Along with the traditional things, like Web services and queued messaging, this latest WCF release adds support for RESTful communication, RSS/ATOM, and an interesting option called the WCF Line-of-Business Adapter SDK. The paper also takes a look at how WCF is used with BizTalk Services.

If you're an expert in WCF, you probably won't get a whole lot out of this paper. If you're wondering why this technology is important, though, or how one approach can be used for many different kinds of communication, you might find it worthwhile.

Introducing the .NET Framework 3.5
# Wednesday, December 26, 2007

When the .NET Framework 3.0 was released, I wrote a series of whitepapers describing the new technologies it contained: WCF, WF, WPF, and Windows CardSpace. I also wrote an overview paper that gave a high-level view of this new version.

With the release of the .NET Framework 3.5, I've updated most of the those papers. (The exception is the paper on Windows CardSpace--that technology hasn't changed.) The updated papers are:

The 3.5 release doesn't contain as many changes as did the move from .NET 2.0 to .NET 3.0. Still, there's lots of interesting new stuff, with plenty of useful additions.
