    Back From Barcelona

    • 0 Comments

    I arrived into SEA yesterday around 3, so I'm feeling a little bit of the 'lag from my week in Barcelona.  A few things to point out:

    • Tim has a fantastic "Vista on the M400" post.  The little dude's getting an upgrade while this gets typed, results in a future post
    • Kudos to who-ever put together this diagram.  I think it could be made a bit better by having links to the section of MSDN which further explains how to dev, say, win32 or hybrid applications, but it's a nice way to represent and download the bits you're interested in. 
    • The long awaited WF perf whitepaper is available, as Paul points out.  As Paul mentions, the 10K empty workflows per second is not a number one should run out a room assuming can be obtained, but there are a few things that I really liked seeing:
      • What happens when we scale out?
      • Should I implement a while loop in my code to loop 1000 times, or should I use the While activity?  This is one of my favorite examples when people ask "How should I think about moving to a WF driven design?"  I like this paper as it explains things in terms of trade-offs.
      • Finally, beneath figure 13, the discussion of the overhead involved with using the tracking service is discussed.  This is important, and it shows the difference between batching and not batching the "transactions" of the tracking service.  Transaction is mentioned in quotes as these have little to do with System.Transactions, rather when tracking data is written to the database.  The number to notice here is not just workflows per second, but also the increased load on the SQL Server.  Again, these are just some things to think about when you start discussing "perf" with workflow.  The papers about 50 pages long, so there's a bunch of stuff to see there.  Check it out!
    • Thanks to everyone who dropped in on my sessions in Barcelona.  I'll be posting some followup information when I get a little time to recover (or at 3:30 tomorrow morning when I am wide awake and thinking it is lunch time in Barcelona :-) )
    • There's also this page, which is a nice gateway into downloading all sorts of the things we talked about at TechEd.

    Did you hear the news, .NET 3.0 is live

    • 0 Comments

    Things got signed off last week, and early yesterday (depending on the timezone), the RTM build was published on MSDN.  James put the details up on the community site, and there's been a ton of people headed to check it out (look at all the trackbacks on James' post).  Thank you to all of the bloggers who have picked up the story and are passing it along.

    So, now what?  Well, there's still plenty of work for me to do, including looking forward to vNext (the great part of evangelism!)  In the short term, I'll be presenting today on Reliabilty, Scalability and Maintainability of workflows hosted in IIS here in Barcelona. I won't be talking about the IIS scenario nearly as much as the other three parts, as well as discussing some performance information.  After the talk, a number of us are headed to a soccer game, which I'm looking forward to.    Tomorrow, Paul Andrew and I are conducting a drop-in clininc for WF, so, if you got questions, stop on by.

    So, what's next for you?  Get the bits, get some training, and start writing workflows!

     

    [updated] realized I had a problem spelling "hear" in the title :-)

    Off to Barcelona!

    I'm in the office this morning, wrapping some things up and then it's wheels up to Barcelona for a week.  Paul, Clemens, Shy and I will all be there hanging out somewhere between our talks and the Connected Systems booths, so stop on by and say hi!
