  • Blog Post: (WF4.5) Using CSharpValue<T> and CSharpReference<T> in .Net 4.5 – Compiling expressions–and changes in Visual Studio generated XAML

    I’ve been publicizing for a while that Visual Studio 11 (still in Beta) supports C# expressions in workflow designer. Of course you might also possibly want to use C# or VB expressions by writing a workflow in code, instead of by building it in Visual Studio. There are actually a couple tricks...
  • Blog Post: (WF4, Xaml) Mc:Ignorable, ViewStates, HintSizes, VisualBasic Settings, and manipulating XAML programmatically

    [Update! There are some bugs with the attached code, see the sequel post for discussion of bug fixes.] My workmate Ramraj mentioned that a long way back (during earlier milestones of WF 4.0) something was invented for XAML called a property reference , which was a feature that in the workflow designer...
  • Blog Post: Best XAML guide ever?

    I just wanted to interrupt the normal flow of posts with a link to a old but wonderful post from Mike Hillberg that I recently found and really like: Being Written by XamlWriter It's full of concise information for figuring out how you can customize your XAML representation for workflow activities...
