My first WWF demo working

Titled “Connecting Activities” it demonstrates how to use the DependencyProperty to pass data from one activity to another.

Visual Studio 2005 web page sulk

I’m working on my project for the .NET 2.0 Competition and I must say that working on a web page in Visual Studio 2005 is a pain. Even more than VS 2003, Microsoft seems to take great delight is piling tonnes of garbage into the style attributes of web controls; forcing you to “clean”...
