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...

Acropolis David Hill's blog is here and the Team Blog is here One nice post on the Team Blog is Extending the Notepad Sample with a Web Browser View Secret Themes in Acropolis Three New Acropolis Videos WCF/SOA/WF/Orcas Jesus Rodriguez on Orcas Durable Services Speaking of WCF, Steve details a really strange finding for both of us: that one way Indigo messages can block. I got the Indigo tracing turned on and it confirmed the results: closing the client proxy blocks until the one way message completes. Why? This seems to defeat the purpose of One Way Messages Harry rounds up the REST responses MAC OS/X OK, so two of my good friends dump Parallels for latest beta of VMWare Fusion . Time to look this weekend! Entity Framework Somehow, I forgot to blog Jeff's post about the good news: Entity Framework to Get Persistence Ignorance (PI) Blogging Good advice from Mr Hanselman on keeping your blog from sucking especially since I have violated some of the principles :) Silverlight/ASP.NET/Expression/Win2K8 Server Brad Abrams covers all of the above in one post Technorati Tags: Orcas.

Winter has finally set in with single digit temps and minus degrees wind chills but still no snow. WPF/Avalon Adam's WPF book is out and flying off the shelves apparently ! I have been looking forward to this one as his COM Interop book is the bible there. Feb CTP of WPF/E! New Docs, SDK and QuickStarts for the above Via Mike Harsh, Dave has put up a new WPF/E sample he built for a recent INETA talk that is a Reflection Editor .NET 3.0 Crash Course - Part 8: WPF Conclusion Tim Sneath , from the WPF Team, has been doing a series on great WPF applications that is up to 6. This hopefully proves that WPF is more than some pretty 3D demo thing and being used in real applications. #1: British Library Turning the Pages , #2: Electric Rain StandOut , #3: 90 Degree Radius Reports , #4: Otto , #5: TF1 , and #6: fnac.com LINQ/ADO.NET Orcas Entity Data Model 101: Part 1 Type safety - LINQ to DataSets Part 2 SOA As mentioned before, Dale Churchward is doing a series on "Proper SOA." He adds A Proper SOA is a Framework , A Proper SOA Must Work With Your Current Infrastructure and Legacy Applications , and A Proper SOA is Flexible Enough to Support Multiple Vendors, Software, and Hardware Harry on the Web Service Software Factory Kzu wrote a niece piece called " Building Software Factories Today " where he outlines some of the challenges and techniques you can use (and we will be using) to make effective factories on today's platform. [via Peter ] Financial and Banking Vertical/Architecture Mike has more on a topic near and dear to me: Software Factories for Financial Services Mike also shows how Microsoft is a clear leader in standards support for our Financial Industry. For us support for standards like SWIFT are critical BizTalk Accelerator for SWIFT Architecture Nick says , "In think that one of the most valuable traits of an enterprise architect is the ability to push gently. In other words, if you find that a team is developing a solution that cannot be integrated or creates Read More...

Workflow/BPM/WCF/SOA David Chappell presents arguments both pro and con as to whether Microsoft qualifies as a BPM vendor. Personally, I think the answer is yes, especially when WF is intergrated into BizTalk 200x and other products. Nicholas Allan continues the excellent Indigo WCF posts with Controlling the Synchronization Process LINQ and Family/CLR PLINQ, which I blogged about some time ago has surfaced again with this post from DonXML where he does some clever reading of Microsoft job posts! to make some educated speculations on the growing importance of Concurrency and Parallellism in the CLR as well as PLINQ . And yes, Don, "the cool kids [ALREADY] realize that WPF, WCF and WF are yesterday's news, and LINQ is where it is at ;)" Speaking of LINQ, see the XMLTeam blog for the announcement of the LINQ to XSD Preview and these links: Here is the link to the LINQ to XSD download . The LINQ to XSD overview document is available separately. You also need the LINQ download (May 2006 CTP) Here is the link to the LINQ to XSD download .

I was goinng to respond to Harry's responses made to Tomas and mine, but Tomas already responded and said everything I would have said: I agree with Tomas that I consider Service Broker a good match for applications with code only in the database, even though it supports more than code completly in the database (I made improper wording in my post indicating it did not) I agree with Tomas that there is a world of difference between "access a database" (99% of apps) vs. database-driven (see Tomas' definition). I said I tend away from these kinds of architectures these days as I see the power of domain-driven architectures (see Nilson). Obviously, there is no one architecture for every kind of problem I also don't get the whole "two types of service architects question" either and that a good architect will choose the right style for the right scenario I'd have to agree with Tomas again what Harry calls "Long running services" are really just a specific case of "Long running processes" and SSSB is too low-level for that. WF and BizTalk get me out of writing that infrastructure that is needed to be built out. But maybe I'm an idiot too and need to get hit with the clue stick as well Technorati Tags: SOA , Service Oriented Architecture , Windows Communication Foundation , Software Architecture , Windows Workflow Foundation , Microsoft Share this post: Email it! | bookmark it! | digg it! | reddit! | kick it!
