问题
I've written a Silverlight application that does not scale when I change from 96 dpi to 120 dpi The text and graphics does not change physical size on the screen as measured by a ruler. I've read in various places that Silverlight should adjust to changes in DPI configuration. The non-Silverlight portion of the web page scales as expected. It seems as if the Silverlight plugin is using Pixels as the unit of measure rather than 1/96 inch. What's the explanation?
I'm running Windows XP and setting the DPI in Wndows XPdesktop properties / settings / general / DPI Setting.

This wont help if you're after measurable coordinates (ie: displaying an accurate ruler in your app), but if you want your UI to be resolution independent, you can wrap it with a ViewBox, which is part of the Silverlight Toolkit
