So, since I am out here in Irvine CA for our annual meeting, and I have just pushed out a Plaxo update to everyone, I guess it's time to let you all know that I have joined Neudesic as a Principal Consultant II, heading/responsible for the Connected Systems/SOA practice for the East Coast. I will have a bit more to say soon. I would expect this blog to change focus to SOA, BizTalk, WCF, WF, and all Connected Systems especially in large Enterprise accounts that is now my respoinsibility to run and enable the growth of. We have a lot of openings for experienced people with at least 7-10 years experience and I have a team to build for the East Coast so contact me if you would like to be part of it. Read More...

I have been working with the Office Live Services Beta for some months now. They just went live with my site over the weekend (although I still have to work on the domain name transfer) and it looks pretty good! I have a new Header and Home Page design. I have added my How-To STS/Window Authentication with ADAM/AD, Roles in AzMan with WCF to the refurbished WCF page . I added a new Domain Driven Design page under Software Engineering . My Presentations, as always are here . Hey, what else am I going to do while I am waiting for my flight? I would like and appreciate any and all feedback as comments here. What's good? What's bad? Knowing my blog and its subjects, what would you like to see?

Still real tired from my Oklahoma trip , partying with Raymond sure is exhausting-). Agile/Development Tools On my short list for some time now, is to switch from NUnit to the definitely superior MbUnit. My friend Andrew has done some great work with this tool and he has a new release out with the beta 1 release of MbUnit 2.4. New features in this drop. I really need to switch and get my team to switch over. It's just been an inertia thing with NUNit as I knew all along MbUnit was better Testing private methods for .NET 2.0 rom Ben Hall. Database rollback support for .NET 2.0 from Cathal Connolly and Todd Menier. NUnit style explicit support from Graham Hey. Speaking of NUnit, they also have a new release, NUnit 2.4 Release Candidate (2.4.0). The Release Notes are here and include some nice features: A new syntax and internal architecture for Asserts is being introduced in this release, based on the notion of constraints found in JMock and NMock. The Assert.That method is used to make an assertion based on a constraint Assert.That( actual, constraint, message, args ); Assert.That( actual, constraint, message ); Assert.That( actual, constraint ); The constraint argument may be specified directly using one of the built-in constraint classes or a user-defined class. It may also be specified using one of the syntax helpers provided as static methods of the Is class, such as Is.Null Is.Empty Is.EqualTo( object ) Is.CollectionContaining( object ) Is.SubsetOf( collection ) SCSF is one of the most visible Microsoft projects being done in an Agile way. They are crazy as us doing one week Iterations. Blaine has some reflections on Iteration 3 . CB brother, Jeremy asks what OSS tools are you using in development? As I answered there, they include: NUnit CruiseControl.Net FitNesseDotNet RhinoMocks Subversion TortoiseSVN Ankh Wiki Speaking of tools. my good buddy Tomas (see you next week!) has a nice list of Text Editors One of the things Raymond and I discussed in Oklahoma was Read More...

Architecture/SOA Blaine Wastell has posted that PAG planning an update of the Smart Client Software Factory to be released in late April of this year. They are encouraging feedback at http://www.codeplex.com/smartclient and enter critical items into the issue tracker ( http://www.codeplex.com/smartclient/WorkItem/List.... ). From where I sit, they have their Priority 1 stuff right with WPF Interoperability. We absolutely need to be able to move to WPF with the existing CAB/SCBAT infrastructure I have been listing posts on WS-RM and its implementation in WCF. Harry Pierson, has an autopost that builds on his recent epiphany about WCF and long running services. He speaks about his conversation with Shy and " At some point in the three years between March 2003 and February 2006, WS-RM went from being the enabler of long running services to "yet another misnamed WS-* protocol". And with it, WCF lost (never had?) the ability to support long running services (as I've written previously )." The main point is that it does not support RM-based durable messaging. As Harry says, "As I said before, lack of support for WS-RM based durable messaging isn't that big a deal. As long as you understand WCF's sweet spot - the current version's sweet spot anyway - and don't try and make it be something it's not, you should be fine. Furthermore, Shy mentions the need for an "interoperable Queued Messaging specification" and wrote that it's something he "expect that we will get to it in the near future". Here's hoping that spec is less flexible than WS-ReliableMessaging." CLR/Tools/Agile/TDD The most indispensable tool in the .NET universe, Reflector, has gone through a big update to V5! As Jamie states , "This is a significant update with lots of refinements and new features. Perhaps most significantly it includes support for C# 3.0 language features such as LINQ query expressions, lambda expressions and extension methods. See my screencast about using Reflector 5.0 from VS Orcas." He also Read More...

Completely buried with two projects and the main one is going to CTP #2 at a major back in Paris/London next week so going to scrape this together quickly. I have also been pairing with Steve back on the main project on solving performance problems - yesterday, he and I optimized a section of the system where an operation was taking 25 to 30 minutes and got it down to 30 seconds! Now that's a good boost! I have much in my head concerning where we are at and my current feelings on being agile, architecture and such but they will have to wait. I tried to blog about the Apple iPhone announcement but couldn't muster up enough interest... Architecture and SOA, Agile SOA and BI Impendence Mismatch Arnon has great comments on a presentation (via Shahid Sah's blog) by Ron Jacobs on the Software Architect's Role. he says, "In this presentation, entitled Architects and the Architecture of Software , Ron compares the architect's role to that of an explorer, advocate, and designer," and "However, I would personally replace "advocate" with "mentor", and "explorer" with a "polymath" or "Renaissance" man. I'd also add a leader and visionary (although Ron mentions that as part of the discussion on explorer)." I agree with his additions, at least how I see my role. He also has some outstanding comments on Agile Iterations and what I really want to write about (and finding) when I have time: "To me, that is just a reminder why JEDUF is important. I find that in projects that are large or overly complex "sacrificing" one, two, or even three iterations for handling technical risks and forming a candidate architecture goes a long way ( and I don't care if this makes my project not agile. I am fine if it is pliant , lagum or what-not)." I am actually finding its quite a bit more than 1-3 Iterations depending on the project and environment. Actually this ties in with Jim's Design Maps . Cazz on Building Software Factories Today Richard Venyard on SOA Algebra WCF/Indigo Harry finds Indigo daunting Read More...

I am SO busy with INETA trips and tons to do at work. Here is what I have stored up for the last week or so. WCF/SOA/Workflow/WF Tomas blogs about something I face every day in WCF with WCF ServiceHost Failures and IDisposable with "The "don't call Close()/Dispose() if faulted" behavior that ServiceHost requires does not work well with IDisposable; it demands a behavior different from the standard IDisposable pattern." We're having a lot of issues with dealing with failures and what to do with them but Tomas definetly states a fundamental problem. Tomas has also WCF, WF and BizTalk Sample Posted with some interesting stuff!! MTOM Interoperability between Oracle Application Server and Windows Communication Foundation Part1: From WCF to Oracle Jesus Rodriguez as well, " I am happy to see this progress: " The Web Services Interoperability Organization (WS-I) announced the publication of three new Working Group Drafts : the Basic Profile 1.2, Basic Security Profile 1.1 and the Reliable Secure Profile 1.0 Usage Scenarios. Advancement of these documents to Working Group Draft status is an invitation to the Web services community to provide technical feedback." I could just list every single post that Mike Taulty writes on WF; they are all that good! In particular, WF and Versioning , MetaStorm and the Workflow Designer , Little Workflow Foundation Sample I could and have done the same with "Nicholas Allen's" posts on Indigo: ListenUriBindingElement , Creating Faults Part 1, and Part 2 CLR How to avoid assembly loads , and Getting the list of loaded assemblies from Richard Lander James Higgs talks about Garbage Collection and the IDisposable interface WPF/Avalon Karsten has an awesome Avalon demo - "The Woodgrove Finance Application is a great demo of how WPF can be used to create better data visualization, in this case for financial data.

So, I have been writing a bunch of posts over the last 14 months, how we have been using Agile, actually full Extreme Programming practices to build a multi-million dollar Enterprise Software platform and application for the banking sector. We certainly have seriously stressed Extreme Programming/Agile techniques to their limits as this is not a small piece of software, but a large Enterprise solution that gets sold into the top banks in the world. We certainly have proven that you can use Extreme Programming/Agile techniques to build a 1.8 million dollar Enterprise product family. have talked about being an Agile Architect and why it's neccessary, how we went to CTP in July , the Process we use, our tools , and even our failings . So, after 48 Iterations we finished all the functionality we had agreed with Business was necessary for a "Phase I" delivery of our Next Generation/V5.0 product, as our Next Generation architecture will span an ambitious set of goals and products on top of this platform. Business and Development agreed together that we would stop and start a three week Iteration of fixing bugs in our backlog, testing and eating our dog food. In Extreme Programming, you are really not supposed to carry over bugs out of the Iteration but this was extremely hard with one week Iterations. We turned out very well overall as all the testing found just over 100 total bugs for 14 months work which is an order of magnitude less bugs than our previous product development techniques. In addition, we have over 1,000 unit tests and the code is well factored, clean and maintanable. The best part is the whole team understands it, not individuals. I actually haven't written about it but I have been working as Agile Architect the last few months on the next phase and not as part of the Iterations directly. These involve a whole lot of Workflow, Reporting and much more. Anyhow, I made a stand with my management the last 3 weeks and insisted that I code and Read More...

Lots of great stuff this time. CLR/Interop There has always been a ton of confusion about CLR assembly version numbers since 1999 and a lot of people don't understand all the different version numbers. Luckily, Richard is starting a series on them with the first being the Native File Version which of course has nothing to do with CLR Versioning. Back to Interop - Mike Stall wisely says Marshal Opaque Structs as IntPtr Instead of Byte[] Speaking of Mike, he's got a very good Table of Cool .NET Tools if you work at this level WPF/Avalon Mike Swanson lists More WPF Conversion Tools, Including VB6 to XAML Karsten s ays, "If you are a WPF developer, you must read Optimizing WPF Application Performance " Anthony clarifies the difference between Microsoft Visual Studio codename "Orcas" CTPs and "Visual Studio 2005 extensions for .NET 3.0 (WCF & WPF), November 2006 CTP". WCF/SOA/Workflow Pablo has three Recommendations to Design Message Contracts . I agree with all three. Number 1 about not including business behavior in the message but using simple DTOs across has been the hardest for us to achieve.

Workflow/BPM/WCF/SOA David Chappell presents arguments both pro and con as to whether Microsoft qualifies as a BPM vendor. Personally, I think the answer is yes, especially when WF is intergrated into BizTalk 200x and other products. Nicholas Allan continues the excellent Indigo WCF posts with Controlling the Synchronization Process LINQ and Family/CLR PLINQ, which I blogged about some time ago has surfaced again with this post from DonXML where he does some clever reading of Microsoft job posts! to make some educated speculations on the growing importance of Concurrency and Parallellism in the CLR as well as PLINQ . And yes, Don, "the cool kids [ALREADY] realize that WPF, WCF and WF are yesterday's news, and LINQ is where it is at ;)" Speaking of LINQ, see the XMLTeam blog for the announcement of the LINQ to XSD Preview and these links: Here is the link to the LINQ to XSD download . The LINQ to XSD overview document is available separately. You also need the LINQ download (May 2006 CTP) Here is the link to the LINQ to XSD download .

Wow, four days in a row, gol darn, I might just be getting predictable and dependable with these posts-). Agile/Extreme Programming The Halloween/Nov Carnival of Agilis ts is up! There is a great section called "What Makes a method Agile" and this which I'll take the liberty of quoting in its entirety, " Robin Dymond questioned the agileness of the MSF for Agile process template by asking Who the hell is Ron Miller and WHY is he redefining Agile for MSF in the Scrumdevelopment Yahoo! Groups discussion. While this is a long discussion, many thought leaders participated including Ken Schwaber, Mike Cohn, David Anderson, Scott Ambler, Ron Jeffries, and others. David Anderson has a follow-up blog post ." Expresso Fueled Agile Development (great name! I'm French Roast Fueled at the moment!) points out that Ideal Day's Aren't... . Martin hits on the head, as usual, with FeatureDevotion , "The key to beating off the waterfall is to realize that, as Dan puts it, agilists value Outcomes over Features. The feature list is a valuable tool, but it's a means not an end. What really matters is the overall outcome, which I think of as value to the customers."

Sipping the first cup of coffee, ah yes, there's a possibility I'll be awake soon... Windows Vista The big news is a major new release of Vista, Build 5472 is available now on Connect and I believe its good enough to make a public release on MSDN Extreme Programming/Agile I'm thrilled to see my good friend and Agile Guru Jim Shore's announcement about his first fully-accredited XP course !! Jim is a consultant on my team and he can make your organization go wicked fast and produce great software too. Notice, "XP course", not Agile. Interview with Andy Hunt (of Pragmatic Programmers) on thier new book, Practices of an Agile Developer TDD Worst Practice: Test Driven Debugging ; I hate when people do this and say they are doing TDD. I've said it once, I'll say it again; if you are spending time in the debugger for logic and business verification, you are wasting your companies money and time. Write a test. The debugger is only for very weird, intractable exceptional situations where there is no other recourse. If you see every testing situation this way, well you need to learn about TDD-) ...more coming CLR Greg Young continues his exceptional blogging at a level that excites me with Performance: String Reverse .

Welcome new readers! There are a number of great posts that caught my attention today. In addition, I have started my 3rd CAB article to be posted here as well as getting my Syracuse WCF slides up on the site. Agile/Extreme Programming/TDD Now, Scott Ambler has taken the ugly heavyweight monstrosity, Rational Unified Process (RUP) and tried to morph it into the Agile Unified Process (AUP) . I have a lot of respect for Scott and his huge contributions to many areas of Agile but I am frankly sick and tired of making Extreme Programming politically correct for brain-dead software companies and watering it down further and further with these kind of things. The tendency these days is to further dulute "Agile" (I hate that term) methodologies to make them palatable. Enough.

You know what? Owning a pool really sucks-). Oh, it’s great to go in but not a lot of fun spending most of every Saturday going to the pool shop getting the water levels measured, spending $100 a week on chemicals, spending the rest of the day applying such chemicals, and endless vacuuming. Plus I have no F*&^^ idea what I’m doing-). Anyone sympathize? I have a whole bunch of stuff saved up since I couldn’t blog because even with 8 of us busting our humps we totally blew this Iteration (more later) and we’re all working in pieces this weekend (Yes, even on an Agile team!). It was a really awesome week for Ruby, especially in CLR land: Ruby/Rails Great news from John Gough (author of still the best CLR compiler book 4 years later) and crew at Queensland, with the preliminary Beta release of the Gardens Point Ruby.Net compiler download !! John, has some more in-depth analysis here . If you haven’t tried Ruby you owe to yourself to do so as it just may arguably be the most powerful yet simple language out there. Equally awesome news from my pal John Lam , who has released RubyCLR Drop 4. I plan to play with both of these as soon as we ship this Iteration-)). Day 1 report f rom the RailsConf 2006 Day 1 and Day 2 Report . Another Day 1 Report from Robby on Rails. Also Day 2 Part 1 CLR FxCop 1.35 release announced on FxCop blog .

Geez, we just installed WinFX Beta 2 this Iteration and immediately had to deal with a hard to find configuration issue. However, we're also always grateful for new bits that advance WCF closer to shipping. Omri says : Check it out here . This build is based on our "RC1" tree. It's not a final WCF RC1 build but it incorporates all the final programming model tweaks that we made from the Beta2 build we shipped in May. The quality of the WCF bits is high, but not quite at the same level as the final Beta2 release (e.g. the stress results for the Beta2 build were better), but it's reasonably good - it's from the middle of "ask mode" - which is when we stop fixing a whole bunch of bugs and start raising the bug bar, so that we can reduce the churn and increase the stability. The final RC1 build will have a couple hundred additional fixes, so it will definitely be better ("go-live" quality), but we absolutely encourage folks to download this June CTP for new projects or for porting from Beta2. The first part seems to say it's not the same high quality as Beta 2 but then it seems the opposite: that it's recommended for people like us to upgrade for porting from Beta2 . Download link to the SDK now fixed . Technorati Tags: CLR , WCF , Windows Communication Foundation , SOA , Microsoft Share this post: Email it! | bookmark it! | digg it! | reddit! | kick it!

A quick reminder while I sit here polishing up my new demos and slides, that I will be speaking on SOA with Indigo tonight at Philly.NET . This is a new talk, even revised from the DevTeach one which got all 10 out of 10's. The demos take on Indigo from the ground up with just TextPad and the WinFX err .NET Framework 3 libraries. Please register and come on out! Extra Bonus: I have some brand new demos with a certain other WinFX, err, .NET Framwork 3 technology!! Abstract : The term SOA has become ubiquitous in our industry. Unfortunately that has lead to massive hype that makes it difficult to understand and distinguish the real value of adapting SOA principles. In my judgment, the definition suffers from technology centric views that are based on the technology environment currently in use. Sam will concentrate on the Design Patterns that distinguish Service Orientatation and how to apply them to your designs. Upon these principles, we look at their real-world implementation in WCF ("Indigo") and using WCF for real world demos giving a through overview of WCF.
