I have been real busy, among other things, doing a full review and change cycle on my Asynchronous Messaging and Event-Driven Architecture talk that I am doing tonight. The entire deck has changed. There has been even more strides towards full asynchronous messaging. To that end, I have worked with the CSD folks to truly understand the behavior of the One Way messaging and its implications on blocking/asynchronous behavior. I will present those findings tonight. I will be be taking my Advanced WCF: Asynchronous Messaging and Event-Driven Architectures talk to the July 31st meeting of PhillyNJ, which is a sub-chapter of the excellent Philly.NET group . I am real pleased, that my friend, Hilary Cotter, is speaking first on SQL Replication for Developers. Come on out!! Hilary Cotter - SQL Replication for Developers In this session SQL Server MVP and replication guru Hilary Cotter explains the essentials of SQL Server replication for developers. Hilary covers replication concepts, what technology is a best fit for data distribution, application considerations, and the new Sync Services in VS/SQL 2008. This is a high level session designed to help you get productive and presents material in both tsql and c# code. Hilary has been involved in IT for over 20 years. He is a SQL Server consultant specializing in search and replication solutions. He wrote a book on SQL Server replication and is currently working on a SQL Server 2008 Administration book and another book on SQL Server Read More...

Welcome to the 11th article in the series. In this article, I will take a broad detour from the abstract into the concrete with WCF. The title of this article is "Introduction to WCF: Architecture and the "ABCs" of Indigo." BTW, I have been in the Indigo SDR program for over 4 years and the term Indigo has stuck in my mind, so I will use the terms interchangeably. Plus, as I think Don Box said in a presentation, It's spelled W-C-F and pronounced Indigo. The WCF is silent." :) Hello Indigo Step by Step I am going to show you WCF step by step and make it as easy as possible. To that end, I am put both the Sender and Receiver in the same console application and I am not going to use either generated proxies or config files. You would never do this in the real world, but it makes it easy to describe the "ABCs" of WCF. So, let's start with a shell console application that should be totally familiar to you. Run VS2008 and Create a new C# Console application and replace the code with the following. using System; using System.ServiceModel; namespace HelloIndigo { class Program { static void Main() { } } } A Service is a Set of Endpoints A WCF service is a set of endpoints that provide Read More...

This is 9th of a series. I haven’t really received much feedback. Please let me know if this is useful, if posts too long, too abstract, your thoughts. Symptoms of a Problem, Diagnosis and Why SOA? Dynamic IT to Support the Agile Business and Business Benefits of SOA What is Service Orientation? What is SOA? The Many Definitions, a Working Definition, the Four Tenets What is a Service? The Four Tenets of SOA Service Architectural Patterns The Current State of SOA and How to Make the Paradigm Shift Realization of SOA with Web Services, Web Services Standards, 1st Gen and 2nd Gen, Web standards Microsoft IO What SOA Design Approach Should I Take? Now, that we have gone broad and general across IT, we need to look at at a Design Approach for Identifying, Designing and Building Services. Should we go Top-Down or Bottom Up? The answer is neither or actually a combination of both together with Agile techniques. Nick Malik had a couple of landmark posts that influenced a lot of thinking, especially mine in the whole approach of SOA. The first was “Bottom-Up SOA is harmful and should be discouraged,” where he laid out the three kinds of SOA: “There are three schools of thought around "how to build an Enterprise Service Oriented Architecture." They are: Top down - central group decides everything and the dev teams adopt them. Bottom up - central group provides a directory and dev teams make whatever services they want. Dev teams go to the directory to find services Read More...

I have posted the Slides and the Source Code for the 3/17/2008 Lehigh Valley .NET presentation on Advanced WCF - Asynchronous Messaging and EDA. The code is all VS2008/.NET 3.5. The last demo with Neuron does NOT include the ESB.dll but the code is all there to indicate how many lines of code needed to implement Pub/Sub (3) vs. all the WCF code in the List Based Pub Sub sample for WCF (lots).

I mentioned that I had been doing a bit of Neuron development with Marty Wasznicky and David Pallmann . Hey, my blog is even listed up there :) I also have been using Neuron in three different customer engagements and it has provided a lot of value to my customers. We just put up a dedicated site http://www.neuronesb.com . There is a lot of good stuff now and we are also going to put more of a community effort going forward. It now has: Product information Vertical solutions News White papers Case studies and customer testimonials Support resources Discussion forum Check it out!
