The second and third part of my article series on Silverlight and Caching are available NOW at SilverlightShow


Ever wondered how you can leverage Isolatd Storage for caching?  How you can cache items between Silverlight sessions, or even between Silverlight applications?  How you can cache server-side with WCF or WCF RIA Services?  And what about writing your own Silverlight cache provider? 


Part two can be found here (on Isolated Storage), part three here (on server-side caching & a Silverlight cache provider).  Enjoy the read :-)

A lot of questions exist on Silverlight & caching.  And that’s understandable, because there are lots of different caching scenarios you can enable, from XAP caching to Isolated Storage to caching your results server-side.


In these articles (in the end, 3 articles will be published), I try to tackle these various scenarios.  The first article is available online now, in which I talk about XAP Caching and Assembly Caching.  If you’re interested, point your browsers to SilverlightShow, and enjoy the read :-)

A while ago, Gill Cleeren and I wrote an article for Technet Magazine on Silverlight for Business applications, touching on WCF RIA Services, MVVM, …  If you’re an IT professional and interested in starting Silverlight development in your business, you can check it out here.


A few days later, I was interviewed by the same Technet Magazine for Technet Radio.  It’s a 10 minute podcast on the more interesting parts of starting Silverlight development for your business.  So, want to hear me talk on this? Check it out! :-)

As some of you might know, during the day (well... often evenings as well :)) I work at RealDolmen, one of Belgium's biggest ICT companies.  On Tuesday, September 21st we're organizing our very first SimplICiTy day, a free event about innovation in the Microsoft stack.  We've got three different tracks for those willing to attend (a business track, infrastructure track and development track), an expert bar, free food and drinks for the hungry and thirsty, ...  so if you happen to be in the neighbourhood: drop on by! :)


I will be delivering a session on Rich User Interfaces: a Logical (R)evolution.  If you want to learn about why these new technologies are quickly emerging to be the standard way to develop .NET applications, what you can do with them, what you need to start coding them yourself, ... this is the perfect session for you. 


Interested?  Don't forget to register - as said, it's all completely free!

Today (second day after my vacation :-)), I’ve been looking for a solution to a rather nasty memory leak in a Silverlight application.  Typically, you can do this in two ways: by using WinDebug, or through Visual Studio’s Immediate Window.


I’m not going to go into the specifics of both – there are already blog posts about that, you can find a nice overview on how to debug Silverlight apps using WinDBG by Delay, another one by Ning Zhang here, and an overview of using it with the Visual Studio Immediate Window here.


However, I stumbled upon a problem that kept me amused frustrated for a couple of hours.  To be able to debug Silverlight apps this way, you need to load the sos coreclr extension.  Typically, in WinDBG, you’d do this as such:


!loadby sos coreclr


This gave me an “unable to load”-error.  No worries, maybe I had selected the wrong Internet Explorer process?  So I tried the other active processes, and tried loading it again.  Same problem.


Quick check to see if my symbol path was ok:




didn’t make me any wiser – everything looked ok


Right.  So I tried debugging through Visual Studio’s Immediate Window (remember, if you’re trying this you need to enable the unmanaged code / native code debugger in your project properties), and loading the sos coreclr extension there.  Same problem.


You don’t even want to know what happened next.  I tried everything again, and again, and again with the exact path to sos.dll instead of through what was loaded in the iexplore.exe process.  And again in WinDebug.  And again in Visual Studio.  And again by having a look at the process with Process Explorer to see if I didn’t miss the correct process for the 70th time.  And again, in a different order.  Et cetera ad infinitum.


Nothing seemed to work.  So I tried some backtracking: what’s different since I last did this?  Well, I’ve now got a 64 bit processor, running Windows 7 – before I had a 32 bit processor running Windows XP.


So I checked if I had installed the 64 bit version of WinDebug.  Which I had.


And then I finally found the solution.  Although IE is 64 bit on my machine, Silverlight is not (simply doesn’t exist yet)!  So maybe I needed the 32 bit version of WinDebug?  I tried installing this (it can be found in the redistributables you get when installing the Windows SDK – which includes WinDebug) and … problem solved!  Magically, everything started to work as it should.


So, if anyone is looking to track down a Silverlight memory leak on a Windows 7 machine using WinDebug: remember to use the 32 bit version of WinDebug. 


Hope this saves some of you from a few frustrations! ;-)

Gill Cleeren, with whom I wrote this book, posted a blog update with some reviews.  And I’m pleased to say: they’re good, very good even! :-)  Here are some excerpts:


Richard Costall’s review:


Microsoft Silverlight 4 Data and Services Cookbook is a great publication, and worthy of a place any Silverlight developers bookshelf. The formula of ‘recipes’ works well, with well explained, yet simple examples covering almost everything you’d ask when starting out building business applications in Silverlight. It highlights Silverlight 2 and Silverlight 3 functionality differences, yet is right up to date on Silverlight 4.


Damir Tomicic’s review:


Das Buch ist sehr praktisch geschrieben. Der Leser merkt sofort, dass Gill und Kevin die Ansätze selbst ausprobiert und für die Leser optimiert haben. Die gewählte Sprache ist einfach, die Beispiele auch für Anfänger geeignet. Ein guter Einstieg in das Thema.
