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...

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...

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...

Ah Saturday morning where we can sleep in, ah no wait...I have kids to wake me up at the crack of dawn... Software Architecture The PAG folks continue to deliver their goodness with their first weekly drop of the new version of the Smart Client Software Factory and they looked like they brought over some of the cool stuff from the Mobile version: What’s New In this drop, you have the first look at: • New Application Blocks. We have ported over four application blocks that were previously available as part of the Mobile Client Software Factory. We may refactor, remove, replace, this code in the future (we value your input), but we currently have the following: o Disconnected Agent Application Block. This application block provides management features for execution of Web services from occasionally connected smart clients. With a disconnected service agent, the device can maintain a queue of Web service requests when offline (disconnected) (emphasis mine) and then replay them when a connection to the server application becomes available. o Connection Monitor Application Block. This application block monitors and exposes the available connections and the associated networks. o Endpoint Catalog Application Block. This application block provides features to expose the physical addresses and other details of remote services. o Data Access Application Block. This application block provides support for SQL Server Compact Edition. This application block will be replaced when the factory migrates to the next version of Enterprise Library. Jeremy Miller continues his excellent posts and talks about something Steve and I approach in our architecture: Don't Let the Database Dictate Your Object Model . I have to admit to being dragged a bit by Steve into this approach with OR/M and dropping the whole data-centric database-out view I have had for many years.

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...

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 have already said my piece on the Vista launch but also Office 2007 launches today which really rocks. The much better Outlook 2007 is worth the price of admission alone IMHO. Vista and Office Launches Vista Launch Page Bill Gates Keynote European Launch Windows Vista Upgrade Advisor Office 2007 Launch Page Nial Kennedy on launch in San Francisco Microsoft Debuts Vista in Global Marketing Blitz Robert McLaws posts on all those great Vista Updates that finally showed up last night on my Update. Can someone get me to stop playing Hold 'Em Ultimate Extra, my fingers hurt -) Software Architecture/SOA Pablo asks "CRUD Service for Service - Is a Bad Practice?" I think it depends, and as Robert Wilczynski says in the comments, some kinds of CRUD are fine, but the greater anti-pattern is chatty contract/interface. What's your thoughts? Pablo also talks about Services in .NET Part 1 Edward has started a new series of posts about factory basics called 'Factories 201', and he has kicked that off with a post entitled "What are they (concretely)?" [via Jezz Santos ] Arnon continues his excellent architectural writings on his Architect Blog with What Is SOA Anyway?: Part I, Ambiguity and Anyway? Part II, Hype Soma talks about Software Factories [via Harry ] WCF/Web Services/Workflow William Tay makes the very real case for why WS-ReliableMesaging is vital. I mean, when people *** about WS-*, I don't get how its not obvious that "the main characteristics of Web services is communication over unreliable communication channels such as the Internet employing unreliable data transfer protocols such as HTTP, SMTP and FTP" and many of us need things like WS-RM and other standards to build real service-oriented systems that actually do something.

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...

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...
