Building Custom HTTP Help Pages with WCF
Been asked this a few times and needed to figure it out myself, so I put together a post on how to host custom HTTP help pages for your WCF services:

Angle Brackets Are Dead. Long Live XML.
Many people fail to realize that XML can be used to represent many formats beyond the standard text xml encoding that most people recognize. So, I wrote a little post about how WCF takes advantage of this idea to illustrate what is possible when you change the way you think about XML. http://blog.iserviceoriented.com/index.php/2010/02/07/angle-brackets-are-dead-long-live-xml/

Building a Simple Web Server With WCF
Tired of seeing a million examples of using REST support in WCF (which blows) and not a single example that goes beyond the basics everyone knows. So, I wrote a simple web server today using WCF and blogged about it:

Back in Action
Everyone keeps asking me to start blogging again... so I'm finally doing it. I'm back in action after a year or so off from blogging. Been working with WCF 24/7 since joining the Neuron ESB Team and have plenty of WCF tricks to share.

ESB Series: Part 5
Been a really crazy month with a lot of projects all going into production at once. Finally had some time to blog about the progress on my WCF based ESB: http://www.iserviceoriented.com/blog/post/Building+Our+Own+ESB+-+Publish+Subscribe+Part+5.aspx There's been a ton of interest in the project for something that is still very early on. Thanks to everyone who has provided feedback so far.

Entity Framework: Right Problem, Wrong Place
I was listening to the recent .NET rocks episode about the Entity Framework advisory council and it was interesting to hear the team's point of view and the problems they are trying to solve with the Entity Framework. They have nice goals, but there is a fundamental problem here that some of the original database gurus like C.J. Date make quite clear. SQL is flawed. It's not that we need a million object relational mappers or that we need to look at our databases in terms of objects. In fact, that's the opposite of what the relational model was intended to do. When E.F. Codd invented the relational model, he intended for the database to be a collection of facts with relationships to other facts... not a collection of objects. The relational model was supposed to provide a way to look at and work with these facts in different ways, but SQL and modern RDBMS's fall short of what they were supposed to do. Somewhere along the way, the original plans were lost. Instead of building a truely relational storage system, vendors jumped on the semi-relational SQL model. The SQL model ties physical structure closely to the logical data model, which is where a lot of problems start coming into play. This leads to the situations we've all seen where we need to denormalize the data model to get decent performance numbers. It seems to me that the solution to the problem should not start with mapping the data to objects, it should start inside SQL Server itself, transitioning from the flawed world of T-SQL to a true implementation of the relational model as it was intended, a world where the physical model is truely detatched from the logical model.

NServiceBus = Fail?
Finally had a chance to dig into the NServiceBus code. My thoughts are here if you care (I'm sure Udi will respond with his thoughts, so comment there instead of here if you think I'm off base):

Events are your Friend
"Imagine trying to build a desktop application without events. How would you make a button click do what you want? One way would be to open the Button source code and add the code directly. That has approach has obvious problems, not the least of which is that the behavior of the button click will vary from button to button..."
