So, since I am out here in Irvine CA for our annual meeting, and I have just pushed out a Plaxo update to everyone, I guess it's time to let you all know that I have joined Neudesic as a Principal Consultant II, heading/responsible for the Connected Systems/SOA practice for the East Coast. I will have a bit more to say soon. I would expect this blog to change focus to SOA, BizTalk, WCF, WF, and all Connected Systems especially in large Enterprise accounts that is now my respoinsibility to run and enable the growth of. We have a lot of openings for experienced people with at least 7-10 years experience and I have a team to build for the East Coast so contact me if you would like to be part of it. Read More...

Slim pickings today. CLR/.NET Scott Hanselman provides advice on how to partition your app and figuring out the right number of assemblies/libraries WCF/BizTalk Services/WCF Dennis points out that he and John Shewchuk recorded a channel9 video that describes the why and what of BizTalk Services. Its now online here: http://channel9.msdn.com/showpost.aspx?postid=317646 Durable Instance Context sample (via Harry ) Windows Vista Running a dual-monitor setup with Windows Vista Resharper/Software Development Tools Took goodness Jeff Palermo found a hack to make Ctrl-N type discovery work properly (speed up!) in Resharper. Ctrl-N I am finding, is one of the keys to success with Resharper.

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...

I asked Tomas to expand on the details of the issue we faced last Sunday and it's this: What’s going is that you wanted to create a custom, reusable composite StateActivity-derived activity. While WF allows you to create an StateActivity-derived class, it restricts a bit what you can actually do with it. The core problem here is that the way you wanted to use the custom activity was similar (in a fashion) to building a custom composite sequence activity. That’s because when you create such a one (like with Add to Project -> New Item -> New Activity) you have full design-time support for creating your composite, including being able to drag & drop activities into the design surface, setting properties, and so on. Unfortunately, the way the ActivityDesigner is composed for the StateActivity class blocks this because it restricts you from modifying the custom activity at design time when opened “standalone”. In other words, it only allows you the complete design-time magic if the parent of the activity is a StateMachineWorkflow (or another StateActivity itself), which would only normally happen when you’re actually designing the real workflow, * not * when creating your composite. (I hope this is clearer, the terminology can get confusing at times). As you correctly pointed out, the way around this would be to create and attach a custom ActivityDesigner to your custom composite StateActivity-derived activity that didn’t have these restrictions. The reason why so much code would be needed, though, is that the corresponding StateDesigner class is internal, and so you can’t directly extend it and just override a couple of methods. Because of this, to accomplish this one would need to completely implement the designer almost from scratch (of course it would be possible, but nasty, to use reflector to grab the core code for StateDesigner and start from there). To be honest, a * lot * of people have complained in the WF Read More...

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...

So after two days of downloading at broadband speeds, I finally got all the pieces of the Orcas Mrach CTP downloaded. Doublce-clicking on Part1.exe expanded the other 8 RAR files. Once that was done, I used Virtual PC 2007 on top of my Vista Ultimate desktop OS. I left the setting at 1 GB of RAM. I then attached to the VPC image and there I was staring at a Windows Server 2003 Enterprise login. The VPC image seems to be put together well. In addition to Orcas (Visual Studio 9), both SQL Server 2005 and Visual Studio 2005 are present. A nice bonus is that TFS is fully installed saving a lot of work. So far, I have just created a Team Project in VSTS/TFS and the speeds are ok. I am going to be digging in during parts of the weekend, so I'll have more as I go along.

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...

Data/ADO.NET Orcas Two from the ADO.NET team: Entity Client and Nulls - LINQ to DataSets Part 3 Software Architecture/SOA/CAB Udi answers, Can or should SOA be implemented without Web Services? David Chappell on The Three Faces of SOA Eric Newcomer: WS-* vs. REST is not the question Another architect with a chronicle of How CAN and TDD helps doing better designs WCF/CardSpace Richard Turner gives an insightful report on RSA2007 especially on the "demo showed Wachovia 's website running on Corillian 's online banking platform using Arcot Systems ' security engine to generate managed cards and process token requests." Corrillian and Wachovia's work will be important for all of this in this sector as more and more backs embrace CardSpace and Identity management. We are seeing a lot of movement in this area.
