Answer: 
Are you using an absolute layout, where specific X/Y/Height/Width is being defined for every control? If you use other types of layouts, they are more relative to window height/width and automatically handle these issues.
Wrap your entire application in the [Viewbox](http://msdn.microsoft.com/en-us/library/system.windows.controls.viewbox.aspx) control. As long as you don't have rasterized images, nothing will look stretched.
