Hi,
Today I want to share with you some videos about application prototyping in Sketchflow with Expression Blend 4.
One of the new amazing feature of Blend 4.0 is the SharePoint support. In fact, Expression Blend 4 is able to publish your Sketchflow prototypes into SharePoint and in this way you can also collect and combine feedbacks coming from different SharePoint users.

I think Sketchflow is an important and useful mock-up application since allows you to share and discus prototypes in an effectively.

If you want to learn how to use Sketchflow I suggest you to download the following Sketchflow PDF GUIDE: http://www.dynamic-prototyping.com

Remember: prototyping’s activity is not time wasting. It helps in pointing out software requirement and specification allowing to better plan development activities!

Marzio.
