    Its suddenly over 80 degrees here today and went off for a drenching run. Team System/Team Foundation Server Big news of the day is that Microsoft has acquired TeamPlain , which makes the popular TeamPlain Web Access for Team Server. Brian Harry says, "Effective today, TeamPlain is available, at no additional charge, to users who own a Team Foundation Server and can be downloaded from here . It will be accessible by any user properly licensed with a TFS CAL." This is great news as this is the #1 question I always get from people whenever I bring up TFS. I don't know if its a news item but together with one of my IT guys I started standing up a TFS server yesterday. Before everyone panics, my motivation is pure experimentation at this part and I wouldn't use all of it anyhow (I would never leave NUnit and CruiseControl.NET) but I am interested in replacing an internal system + Wiki + other stuff into Work Item Tracking and maybe the source control. I am starting to get sick of Subversion but its seems to be doing right by the team. Speaking of TFS, Microsoft has let loose the plans for Rosario , the next version of TFS that is just past Orcas. Speaking of future plans, the same page has all the plans for the next year for VSTS. Geez, isn't anything secret anymore? :) WCF/Indigo/SOA Michele has been real busy! I know she's at DevConnections this week, the book is close to done (and its going to rock!) and last week she was at SD West 2007 and put up a slew of materials from it including great stuff on Contracts & Versioning, CardSpace and Identity. INETA Speaker Matevz Gacnik delivered an INETA talk on WCF session support, one of the bedrock's of our Service Interface Layer. He has the PPT Code I'm rocking out to Begin The Begin by R.E.M. from the album And I Feel Fine...The Best Of The IRS Years 82-87 Technorati Tags: .NET , Team Foundation Server , VSTS , Visual Studio Team System , Orcas , WCF , Windows Communication Foundation , Indigo , .NET Framework 3 , Microsoft 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?

  • CSD in the Cloud - CSD STS and Relay Services

    As my good friend Tomas notes , the Connected Systems Division (the people that did WSE, Indigo, Workflow and much more) are doing some pretty interesting "Cloud" services. At the moment these are experimental services you can play with but they don't yet have any SLAs or assurances. If that turns out to be the case, it will be a huge step forward and I would jump on it on my project. What do they have? They have an STS: Security Token Service that is an open identity provider that integrates with CardSpace to provide an authentication service. Having implemented a bare bones STS, I know this is not easy work and mine is far from complete. I need to use SAML, WS-Federation, CardSpace/OpenId to integrate with Java platforms and existing authentication providers. This is a HUGE win for us if we don't have to build it and IF Microsoft hosts it with the appopriate SLAs. Next up is the Relay Service which lets you expose a WCF based endpoint/service to the Internet from behind a firewall or NAT. Having worked with two companies in my past, Groove and Adesso, that had Relay Services and groked this area, I am real excited. The Relay Service uses whatever security policies you have and had defined with the STS so its secure. One scenario that is key for us is that we wanted to offer a "Direct" Service to two banks that want to collobrate with each other. We looked at doing that with with Dual Bindings in WCF but of course banks don't want to punch another hole in their firewall so this could be a great solution. Have a look! All this stuff works with the .NET Framework 3.0 and WCF.

    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...
  • 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 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.

    A N&N from Brussels Belgium where I am up in the middle of the night (again I wake up at 3AM!) with my sleep hours all screwed up. I am enjoying my week here nonetheless. I don't know quite what to make of Brussels. Some parts remind me quite a bit of Paris but there is this weird mix of "modern" glass buildings although the style is a bit "older" than such US buildings. I don't know, I'm jet lagged and probably making no sense. The (potential) customer we are visiting is actually quite large > 3,000 employees most in one large building and I have been working hard on a "High Level Technical Document." Its' certainly some BDUF but this is a large SaS type architecture across 3 data centers that has many Enterprise issues (levels of Failover, SLAs, SQL Server Hot Mirroring, Perimeter Zone Security, etc. to deal with and get right. Anyhow, the food is good and there is a lot of espresso-).

He also reminds, "Note that the white paper written about this application is still relevant and worth reading.
