Lately I have been working on design time data and unit testing with respect to MVVM frameworks. Most of the design time data work I have done is in the XAML with interfaces. That brings up another question, does these frameworks ‘blendable’? Unfortunatly I never did any work on Expression Blend, so I switched my focus to Expression Blend for the last two days with design time data in mind. This morning I came across the following link and it is worth sharing and useful any expression blend newbies like me. http://visitmix.com/labs/rosetta/EyesOfBlend/DataTemplates/ If you all have any MUST read for expression blend newbies, please send it to me.
