Ever hear the story of the guy who responded to ScottW's Facebook NJ Developers and DonXML 's same email and gets addicted to Facebook ? CLR/Rotor Phil Haack has a most excellent tip on an easier way to see the Rotor code. Instead of doing the whole multi-hour Rotor unzipping and building dance, you can view most of the code online here ! Design Patterns/UI/CAB/Software Design/Agile Jeremy continues his brilliant series with his Build Your Own CAB #14 . I'm not going to quote the whole title as it has too many buzzwords to type :) Speaking of buzzwords, Chris combines a mouthfull in his most excellent post: NUnit, NBehave, DSLs, Fluent Interfaces - and other popular gibber jabber. You should read it. Windsor/IoC Jeremy Jarrell has started an excellent series on tools that we Agile developers use. The first piece is an excellent down-to-earth tutorial on Windsor, the Inversion of Control (IoC) container piece of the Castle Project , the same guys that bring you MonoRail IronRuby Scott Hanselman continues the Iron Ruby juice with a WPF Sample in IronRuby talking via C# to Wesabe WCF/Distributed .NET Matevz Gacnik has an interesting post where he managed to get distributed transaction scenario working using WCF , MTOM and WS-AtomicTransactions .

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...

Software Design/Agile/XP Ayende provides the substance and answers to Frans in the Working software over Comprehensive documentation and Documentation can be ambiguous in the most insidious ways . Since these posts substantially cover what I like to think I would say and believe (and say it better), I'll let them be the pointers from my Writing Maintainable Code post as they pretty much say it all See also Ayende's earlier Understanding Bad Code WCF/CardSpace Rick Strahl on Hosting a WCF Service in a non-.NET Client Getting CardSpace Tokens Programmatically Technorati Tags: Software Design , Agile Development , Extreme Programming , WCF , Indigo , CardSpace Read More...

Agile/TDD/Software Development MbUnit 2.4 RTM Rhino Commons, Repository<T> and Unit Of Work Setting up Windsor for auto registration of components Acropolis Brad Abrams has a follow-up post that has a lot more information including videos, links and tutorials As I figured, my friend Brad Wilson says it nice and neatly: CAB is dead! Long Live CAB! Glenn follows that up with what you need to know to migrate from CAB to Acropolis ASP.NET/Ajax/Visual Studio ScottGu has been doing these great weekly roll-up posts lately; Here's one from May 31st SQL Server Katmai Yes, there is a CTP already [via Euan ] Ayende has a Developer's Perspective on Katmai Windows Workflow The Page Flow WF sample that Jon showed me is out. It is tremendously useful and includes some nice tooling Speaking of Jon, he posted the code for his WCF and WF session at TechEd Community Ayende quite correctly says, " It's Not a War, It's Not even a hot argument " in response to Kevin . As I said there , "I said something to the effect that there is no war, there is not even violent disagreement. There are passionate people that deeply care about their craft and like to debate ideas. I might see 'can't we just get along?' as just accepting the status quo. I think we should constantly question the status quo, step out of our comfort zones to learn from each other. I have learned a lot by Ayende's questioning personally. I know O/RM for instance is 'new' for many of us and it challenges many assumptions over the years that Microsoft (wrongly) told us over the years with SPs. As I have expanded my horizons, I have learned a lot with the daily use of O/RM in my project and it has changed a lot of what I assumed and knew."

I have spent a lot of time through the night and some today to try to get my personal blog in order after the Mac options didn't pan out. We have a really important, large external release going out to two external banks next Friday but we stopped this week's Iteration to fix bugs that had been found. In XP, you don't keep going when you have bugs, you stop and fix them. VSTS/TFS TFS is still way too hard to install. The install that my experienced IT guy started last week finally got done last night and took him roughly 16 hours of work time to install including SQL Server 2005 Standard. That is still way too long. To "breadboard" TFS, I am putting in my Workflow Architectural Spikes. More later.

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...

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...

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...
