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. I've posted the source code -- there are some good nuggets in here worth exploring." Introducing the XML Assembly Generator Data V1 of Data Read More...

This is one reason why Scott Hanselman calls me an "Interop Beast" -)). We had a thorny COM Interop issue that was causing a crash in certain machine types. Every single pair on the team had worked on it for many hours this week in our Ship Cycle without success. It should have been solved since I was feeding them all the usual Marshal.ReleaseComObject crap again but it refused to be cleaned up. If you remember back from my posts in 2002 , while working with 10 million+ plus lines of COM to interoperate with while I was at Groove, I had run into many thorny lifetime issues. As a review, (for more information read my MSDN articles here and here ), the Runtime Callable Wrapper is a "bridge" between the two very different worlds of managed CLR code and unmanaged code. Its job is to hide all that ugly COM crap from the goodness that is the CLR and feel, smell and taste like any other CLR object. To do this it must perform a tough job as the COM world is completly deterministic and the CLR is completly not as the GC runs when it feels like it. The RCW (usually) has one and only one unmanaged COM reference to the underlying COM object. The problem comes that when you are done using the RCW on the CLR side, you are marking the RCW class for GC but when that GC runs is complelty non-determinstic and probably not going to happen that split second. The issue is that COM wants references cleaned up right away (ref counts-- until 0) and killing off that object or bad things happen, like crashes. So, the RCW is still holding on to that reference while waiting for GC and the underlying reference is still being held. BOOM, comes the crash in many cases, like we faced. In the case, we were trying to interoperate with some old VB6 COM objects from an old legacy previous version of our product that was being driven by a command line script. The first thing is that IDisposale was not completly implemented and so I did this: public void Dispose() { Dispose(true); GC.SuppressFinalize(this); Read More...

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 .

Family morning at the Gentiles means the whole family watching Radiohead from 1994 while waiting for the Starbucks to come... Software Development Ayende points to this great list Nine Things Developers Want More Than Money and asks what excites you as a developer? As I said in a Retrospective last night, its not about money for me or just a job (expressed as "Build Something That Matters"). If I can't have the passion for my project, my career as a Software Architect, taking the responsibility for my own career, than I need to find something else to do because this is far from the least stressful job out there. You had better be in it because you love it and love to create and ship stuff that delights customers. Otherwise I can go weave baskets out in New Mexico... Data/OR/M/Software Architecture Jeff Palermo notes that we'll see Microsoft's OR/M soon and I can't help thinking BFD and its about time. After years of misleading developers that Stored Procs and database-driven architectures and apps were the only way , is too late? Many of us who have been doing this for a while and come out of other environments are already way ahead using Wilson OR/M, NHibernate, LBLgen and others. And everyone gushes "oh, ah, LINQ is so cool!...... I really like my friend Peter's piece Specifications are Like Object-Oriented Messages . A must-read! Avaon/WPF XamlPadX Updated!
