silverlight-4.0

I have a complex project using SilverLight Toolkit's ListBoxDragDropTarget for drag-drop operations and it is maxing CPU. I tried to reproduce the issue in a small sample project, but then it works fine. The problem persists when I remove our custom styles and all other controls from the page, but the page is hosted in another page's ScrollView.

"EnableRedrawRegions" shows that the screen gets redrawn on every frame. My question is this: How can I track down the cause of this constant redrawing?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
