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...

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. Also see his My Least Favorite Kind of Requirements Undocumented WCSF Feature: Global Exception Handling Udi tackles Can, or 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...

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...

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".

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."

Angus, the bulldog has so taken over the house. At least, it's made us more popular with the neighbors. Agile/Extreme Programming I always appreciate the care Jeremy Miller takes in articulating his points and his latest is no exception. In stating his Programming Manifesto , he makes reference to the infamous Agile Manifesto , I find I am in alignment with just about all his well-argued positions, particular, Unit Testing and Testability over Defensive Coding, Tracing, Debugging, and Paranoid Scoping and Explicit Code over Design Time Wizards. Read it all and come up with your own. Martin Fowler takes on PairProgrammingMisconceptions . Some are obvious but three, in my mind, are not: You have to do pair programming if you're doing an agile process Extreme Programming forces you to do Pair-Programming It's only worth pairing on complex code, rote code yields no advantage.

I am still reeling from seeing the Red Hot Chili Peppers with Mars Volta 2 nights ago in Philly at the Wachovia Center. The Peppers were beyond grea t with Frusciante taking a very active lead role. Many of the songs contained a full-out Hendrix-type feedback solo in it that showed the depth of his talents. I think Stadium Arcadium is their best album since Blood, Sex, Magic (which they pulled out the title song the other night!!). You can't beat a start of Can't Stop-> Dani California! Mars Volta is one of my favorite bands (although hard to take at times) and I am listening to the brilliant new Ampheture right now which they played in full the other night. Live, they come off as a wall of sonic noise and Bixler-Zavala wailing singing, an assault on the senses that drove people nuts (my wife wanted to leave!) and their greatness only came through in sporadic moments (Viscera Eyes). Okay, a lot of stuff today. Number one, I want to congratulate my good friend and master of these types of posts, Mike Gunderloy for hitting The Daily Grind 1000 !! Mike is an incredible asset to the community and a terrific writer to boot. If you are one of the rare people not already subscribed, get your ass over there this minute and make it so! I have started to write (for work) a Workflow XOML loader and executor. I want to do something like XamlPad or even Snippet Compiler to execute my workflows. I have the hosting of the runtime down and loading the XAML/XOML. More later.
