Blend error : "a design-time error was detected in the prototype. Exception has been thrown by the target of an invocation" RRS feed

  • Question

  • Hello, 

    I am just started to build a prototype of screens for my student task. I use Microsoft Expression Blend 4 (WMF Sketchflow). While trying to play the prototype by pressing F5, I got an error : "a design-time error was detected in the prototype. Exception has been thrown by the target of an invocation"

    I am not a developer yet and I am definitely a newcomer in the world of Visual Studio products. Somebody pls give me a clue, I have to submit my exercise tomorrow. 

    Thank you in advance for a help. 

    Roman
