The Code Jedi

Using Expressions from Windows Workflow (WF) Designer

Working through the book Beginning WF: Windows Workflow in .NET 4.0 by Mark J. Collins, there came a point where the next step is to add an “Add” activity to the workflow (Chapter 4 for those interested). The method given is to make changes directly to the XAML of the Workflow designer, and it would then appear within the designer when switching out of code mode.

Unfortunately, I had a typo somewhere which my brain couldn’t reconcile immediately at this late hour, and took me thirty (30!) minutes and two re-types to get right. It didn’t help that there was no IntelliSense provided from within the XML editor, as I am accustomed to having with typical XAML code when doing WPF or Silverlight development.
