I’ve discussed Reactive Extensions with a few people after my Rx talk last week and thought I’d clear up some confusion by clarifying on this blog… One thing to know about Reactive Extensions is that simply going from pull model (enumerating) to push model (observing) doesn’t give you immediate background...

While I was watching the Silverlight TV episode on common WCF service issues with Silverlight ( Silverlight TV 46: What's Wrong with my WCF Service? ) I remembered one more issue that bit my neck a while back and thought it was worth pointing it out again... It was one of those “Service returned...

Another NTK has ended, and in my opinion, this year’s conference was one of the greatest and most enjoyable for the past few years. This is a list of sessions I had (alone or with co-speakers), along with the PowerPoint slide decks (all in Slovenian Language): Silverlight and MEF [The Photo Gallery application...

Named & optional parameters are a new C# language feature coming up with .NET FX 4.0 and guess what… it’s in Silverlight 4 as well! Optional parameters will come very useful when defining complex APIs where you would usually have to provide several overloads for the same method for it to make sense...

The current Silverlight version is v3, with v4 in the making (in Beta 1 at the time of this posting). Silverlight 4 is bringing a lot of new features in the core framework and to use them, you would have to migrate your applications to the latest version, once it gets released. And that would require...

My two-part article on rebuilding an existing Silverlight application to use MEF (Managed Extensibility Framework) for “selective composition” is now live on SilverlightShow.net ( part 1 , part 2 ). I took my Halloween Gallery application and made it pluggable so I can pull in different themes throughout...

Following up on The ultimate hack for Silverlight in Blend post from Josh Smith, I tried to make Blend display pictures from the My Pictures folder right in my Silverlight application. Needless to say, it worked as advertised :) The ViewModel is set through d:DataContext: public class MainPageViewModel...

A few of my Silverlight articles were published on the SilverlightShow site this past two months. The first one is an introduction to Silverlight/(WPF)/Blend behaviors, where I create a Silverlight Halloween Sound Player without writing a single line of code – the application is composed entirely in...

Fooling around with Silverlight’s WebCam support. The application below will let you zoom in and out of WebCam capture and pan around. Nothing special, just a quick POC for the project I’m building. Silverlight 4 required . tweetmeme_url = 'http://tozon.info/blog/post/2009/12/21/Silverlight-4-WebCam...

In my post -NTK09 conference blog post I mentioned one of my MVVM demos was about sharing a ViewModel between WPF , Silverlight and even Windows Forms application. I got a lot of requests for posting sample code online since then, which I intended to do earlier, but because the sample application code...

In my previous post , I wrote about “the first line of defense” against inputting invalid data in Silverlight applications (or any kind of application, for that matter) – preventing the user from entering invalid data through some an input form. Input form fields are commonly directly bound to the underlying...

This is a short tip for constraining your Silverlight applications to a single instance, something that’s quite popular in the desktop applications world. What you want to do is allow only the first instance of your application while rejecting all subsequent instances. Silverlight 3 introduced a way...

With Halloween around the corner, it’s time for some scary photos… In this post I’ll explain how I built my demo application I showed at my Windows 7 Launch talk . Expression Blend 3 shipped with a few interesting samples, available for immediate use. One of them is called Wall3D (Silverlight 3) and...

On this year’s Bleeding Edge conference I had a talk on debugging with my fellow SQL Server MVP . While he covered some common pitfalls developers make on the SQL Server side, I focused on the Silverlight side of development and debugging: possible issues with application deployment options and strategies...
