Do you have a wonderful Silverlight application that you enjoy running in all of the glorious browser flavors available, only to find out that some weird quirky issue pops up in our old friend, Internet Explorer version 6.0 (IE6)?

I’m working on an exciting project using Silverlight and the PRISM framework/Composite Application Library. It is perfect for our use as a rich, interactive line of business application that has a lot of features.

A Twist on the Observer Pattern

The observer pattern is well established and used. The typical scenario is to register to an class and then allow your Notify method to be called. This often involves keeping an internal list of observers and then iterating them to notify that something has changed. I had a situation recently that warranted a lighter weight…

More Confusion over “by ref” versus “Reference Types”

Apparently my prior blog post about “by ref” versus “reference type” caused quite a stir and a bit of confusion. I think the underlying issue is that people confuse “by ref” as having something to do with “reference types.” They are not the same. Reference types and value types are about instances, passing by ref…

Editing WPF Controls in Expression Blend

This is one of those quirks that until you try it, you may not know it exists or what the answer is. I am working on a WPF project and have a separate control library (actually, a module because I am using the Component Application Guidance/PRISM pattern). I pulled it into Expression Blend and was…

Ref Keyword for Reference Types

The Ref keyword is well known. It indicates that you are passing a reference, not a value, to a method. That means that if the method modifies the value, the changes will be apparent to the calling method as well. Where I see a lot of confusion, however, is what happens when dealing with reference…

Pragmatic Reflection on Singletons
