    TGIF!! I am super busy right now designing a multi-CPU/multi-threaded Parallel Calculation Engine and diving into the science of Parallel Computing. I'll have some links when I get a chance. Windows Workflow Tomas talks about Silver , the integration of WF + WCF. The marriage is sorely needed because, as I have posted here , the current situation well, sucks. Silver uses Queues and bypasses EDS completely, which is what anyone needs to do to have any real success of communication into Workflows. Because we could not use Orcas here, we actually implemented our own version of the mechanism to avoid the hell that is EDS. Jon Flanders , the guy that helped me with the above, also worked on the PageFlow Sample that has been updated to V1.1 Even more interesting is that he has working on this project for hosting Workflows inside of BizTalk. This is very interesting as developing your own host is so not trivial, but I totally challenge Paul's assertion that " No BizTalk Experience Required ." Architecture Steve Jones has a post YAGNI, Requirements and why scaling isn't always important that I totally agree with and is in-line with what I try to do as an " Agile Architect ": "Split information exchange from the business services, and worry about the scaling that is appropriate for your information exchange. Don't worry about technical purity and some "wonder" architectural approach. Don't over engineer because if you do X (or R) then it will scale to 100,000 users, but your requirements say "6". Software Design/Agile/XP/Design Patterns/CAB Number 11 for Jeremy in his continuing excellent series on UI Design Patterns in Build your own CAB #11 - Event Aggregator Jeremy has another big AMEN post for me in his Design for Testability , which really goes with my Writing Maintainable Code post, "" Done, done, done " isn't just writing code. It's writing code and verifying that that code works correctly. Read More...

    Sitting here on Saturday morning with a nice cup of Kona coffee. There just is no better coffee in the world. Strong but deceivingly smooth. I really miss our former annual trips to the Big Island that we used to take with my Father-In-Law and family before he got ill. We used to go up in the hills and buy direct from the growers. Umm, nothing better. The coffee may actually help me get over my funk morning as there is now a lot going on my personal life but you know you never get to blog what really matters Agile/Extreme Programming/Tools While Steve was off having a baby , I went back into the team pairing full time for this Iteration rather than doing do the advance work on Workflow and stuff. It felt really good and of course it was a challenge for me, as many of the particulars of the system have changed since I last paired and I had to actually relies on my pair more. What floored me, even though it shouldn't at this point, is just how good this team has gotten. Every single person on the team could explain any place in the code at any time and we were able to evolve the design and code together. It still blows me away the power of pair programming BTW, we are working on our THIRD release of our Collateral Management tools and architecture to at least two Top 50 Banks! Ayende has released Rhino Mocks 3.0 , the premier Mocking solution on .NET IMHO He was also on .NET Rocks talking about NHibernate and Rhino Mocks Since he still had time after the last two somehow, he also put out an hour long screen cast about Rhino Mocks Jeremy is Code Complete on Structure Map 2.0 Financial and Banking Mike Walker announces the OBA Reference Application Pack for Loan Origination Systems (OR-Loss ). This is a lot of great stuff here Mike is also doing a Financial Services Unwrapped IV Webcast Workflow Paul Andrews blogs about the 3rd performance paper released for WF Sylvain blogs that K2 BlackPearl Beta 1 TR2 is available.

    Smart Clients/Orcas I am extremely pleased to see the .NET Framework (and Microsoft) finally gain the offline sync services that I have been talking about for quite a few years in my work at Groove and Adesso . You will be able to do synchronization from WinForms and WPF apps that you could do from Groove apps (in my case WinForms) 4 years ago and Adesso 2-3 years ago now.

    Thank God, its Friday. Even after a full 32 ounces of strong Starbucks coffee, I still fell asleep on the train on the way in. Entity Framework/OR/M/LINQ The excellent Entity Framework discussions continue with Scott Bellware's fine Entity Framework Challenges Architecture One of my core principles of Agile Architecture that I will talk about in Monteal next month is that of Lighweight Modeling. Core to that, is what Scott Bellware said, That's "Model-Driven", not "Diagram Driven ." Like Scott says, I also put my model into the domain and evolving that model. I too don't find much use for diagrams, particuarly the waste of time Whitehorse ones or worse yet the Rational Rose ones. But, as Jeremy noted from his discussion with me , I *do* find the use of a very small subset of UML used rather precisely in drawing quick, non-durable model diagrams on the board. In fact, Jim Shore and I taught our team to do it in any part of the code base at any time. Harry channeling Nick , "Nick Malik on enterprise architecture : "Enterprise Architecture is not about 'building solutions right'. Enterprise Architecture is about 'building the right solutions'. Agile/Good Software Design Jeremy on the DRY principle and the Wormhole Anti-Pattern He also points to the great piece Top ten things ten years of professional software development has taught me . Agreed with all of it Jonathan has a niece piece that I vigorously nodded my head in agreement with, Pair Programming improves your Communication Skills .NET/CLR Scott Hanselman - A Better Way for Click Once and Firefox . Yes!! Misc I was ROTFL when I read Lazycoder's rant , "Save me from having to type more angle brackets. Please. I’m tired of $#@$@ angle brackets. My “,” and “.” keys are worn to a nub. My shift key is floppy and has no spring left.No more angle-bracket based UI. EVER." Technorati Tags: .NET , Orcas , Entity Framework , Read More...
  • New and Notable 150!!

    This is it, the big 150! The first New and Notable was on May 19, 2003 , (my first post was March 29, 2002 ) and I paid homage to the master, "I have always admired Mike's ability to look at the world out there and put it all into one great post, The Daily Grind . While I can't pretend to have Mike's writing ability, I would like to start moving to something similar instead of multiple seperate posts." I wish I had the discipline of Mike because if I posted daily I would be well towards 1000 instead of 150-) but hey I'm pretty proud of my record. I love this community and in the last 25 years this community (and Microsoft) have been real good to me and my family. I hope that what I have been picking here has been of good use to the community to keep you informed on key .NET activities as well as the architectural and design side. Thus, I go forth and pick: Entity Framework, ADO.NET 3, Orcas, MVP Summit One of the best writers in the community today is certainly Jeremy Miller . His latest post, MVP Summit Recapped: Linq for Entities, MonoRail, and Shameless Name Dropping , is a fine example of why. In one post, he is able to write quite elequently on complex subjects like the subtle design flaws in Entity Framework 3 and why WF 4 will rock your world. He is able to take a technology, stick to his design principles and stand his ground, educating and helping all involved achieve something better than was there before. He certainly wasn't the only one of us doing that but his post really captures the core design principles of no infrastructure code in business logic classes. Infrastructure is Infrastructure, business logic is business logic. We want the same thing: No marker interfaces, no codegen, no partial classes. Just plain "PO" and support for the Unit of Work pattern. David Laribee also talks on this area and makes clear that its a vision thing that doesn't really compare to NHibernate which is just OR/M; it's a full Read More...
  • Refurbished New Home Site

    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?

    Yup, I'm still stuck in Seattle and I still feel like crap. Tomas just went off to the airport and I feel like the last MVP left in Seattle. Just want to get out of here and home but can't do that until tomorrow night. Lots of stuff stored up Entity Framework/ADO.NET 3/ORM/ASP.NET/MonoRail I consider my (and all the Code Better guys) biggest contribution to the whole Summit has been our conversations with the Microsoft Data Team on Linq for Entities . I would like to thank the Microsoft guys for being so open to feedback and understanding us In the meantime, Ayende went and did LINQ for NHibernate in his spare Time; does this man ever sleep???? Actually the second proudest moment came some of us CB bloggers with the special meeting with Scott Guthrie on how to make ASP.Net better support MVC much like Rails and MonoRail. My dissatisfaction with ASP.NET is well known and the reasons are expressed well by Ayende here on the leaky abstractions with WebForms and Jeremy Miller here . I expressed many times on my blog that I would just as soon go to Ruby on Rails if I had to do any Web stuff today. Several of the CB bloggers let me know about the goodness that is MonoRail. It's really awesome to see ScottGu have an MVC framework in the works as Jeffery talks about here Inheritance in the Entity Framework is the latest from the Data Team They also updated the 101 LINQ Samples that were included in the March CTP have now been updated to include the 101 LINQ to Entities Samples. To check out the newest samples download from here . Software Architecture/WCF/SOA Nice discussion from Harry on answering Dr. Nick's questions on SSB/WCF The Feb 2007 release of both the GAT and GAX have been released with Vista support but Harry has noted that you have to re-install all your guidance packages which is not so good Christian Weyer has some great slide decks from DevWeek 2007 Matias has an awesome post, " The holy grail of Enterprise SOA security " about SOA Enterprise Security using WCF Read More...

  • ADO.NET 3 - Entity Framework without Persistance Ignorance

    Ayende says, " Here is an interesting discussion about this topic. Apperantly you will not be able to just take any object and persist it using the Entity Framework. You need to either inherit from a base class, or (in the future) implement a set of interfaces. I can't figure out what the reason for that is. It is not as if supporting POCO persistance ignorance is hard or complicate the framework (at least not compare to the issues of the persistance and querying themselves). One of the goals for NHibernate is that you should be able to develop your application where only the controller has a reference to NHibernate, nothing else. " Just know that myself, Jeremy Miller, Scott Bellware, Richard Llelyn are taking the Entity folks apart about this as we speak (at the Summit) and teaching them about NHibernate.

    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...
  • Latest on Agile Project, Reorgs, and Interop

    In a post on January 25th , I said, "I posted yesterday that we had shipped our Enterprise Collateral Management solution based on our new architecture. As I said, we still have a lot more to do ." I provided a concise list of the methodologies, technologies and tools that we used in our 14 month cycle. To update where we are now, it will be necessary for me to give a little more context. First, when I mention "our company", we are actually a Division exclusively devoted to Collateral Management. This division, in turn is part of a much larger worldwide company that has at least 6 more financial sector products dealing with other aspects of managing risk. That company then, in turn is part of a huge Ratings company. The rest of the products are (mostly) integrated into one suite that we sell. Ours is not. One reason is that the various products have been organized into self-contained product groups. That means that we had our own development, marketing, sales, product and management for just Collateral Management. Five or six weeks ago, our company went through a rather large reorganization that aligned things by a global R&D, global Marketing, etc. I think this is an extremely good thing. Our product is now "owned" by R&D which also owns all the other products that are part of the suite and otherwise and we are detached from product so we can focus on development. We can also look at integrating into the suite and bi-directional learning. One consequence of this is now instead of my boss reporting to a VP of Collateral Management, he reports to a Senior Director in R&D who owns a product out of our large offices in Manhattan. The cool thing is that Josh Madden is a 20 year+ veteran developer/architect like me who has done great things in the Financial area for companies like Reuters. He gets development. The other cool thing is that his other product group also uses a lot of Agile techniques and greatly appreciates our total XP environment. One more thing: Read More...

    I haven't felt like blogging much lately. Some of that is due to how much is going on at work (much more on that when I feel like it) but I have also haven't really felt jazzed about blogging lately. I want to, and am starting to devote more time to get myself into the gym and my family, both of which have higher priority, of course. I should at least empty out my flagged items in Feed Demon as the size of the list drives me crazy-). WPF/WPF/Avalon My good buddy Walt wants to know " What are the Top Five Things you want to know about WPF/e ?" He is speaking at several conferences this year on the subject, so if you want to influence his choices, head on over! Simon talks about the Regatta Manager as his #7 Great WPF application and as the 2nd production WPF ever . It definitely seems that WPF is picking up some real momentum in real applications vs demos Speaking of that, Tim Sneath continues his series with Great WPF Applications #7: Skandia Cowes Week CourseSetter Software Architecture/SOA Mario Szpusztra posts his whitepaper on his point-of-view on Microsoft's strategies around Service Orientation, BPM and ESB. Its a good read I agree with Harry on his reaction to Anne Manes of the Burton Group says the time is right for UDDI , calling it the "foundation for governance". I agree that UDDI may be a piece of the puzzle but I have seen nearly zero uptake on UDDI. As Harry says it's all about "desire" rather than discoverability Arnon continues his "What is SOA Anyway?" series with Part 4: SOA Defined and Part 5: Summary SQL Server/Data Congrats to Data Dude team on shipping ! You can get it here , more details from Gert here WCF/Indigo A nice series of posts emerged on Indigo beginning with a post that Harry sent me and asked me to review. I think Harry is right on in his How I Learned to Stop Worrying and Love WCF with his realizations about the relationship between duplex contracts and durable services.

    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.
