Hat tip to John Goldsmith, VISIO MVP and all round nice guy.   For this great information.

I often need to mock up Mobile (and if forced ) desktop user interface layouts.     

Normally I do this straight in visual studio.    However  I may now move to Visio to achieve  this thanks to these stencil templates

I wonder, if Yahoo will ever release these as WPF controls ?
