c# - Translucent background like iOS/OS X and Windows 10 startmenu in WPF apps -

-

ios, mac os x , windows 10 support translucent background. there documented api in windows 10 extend effect in wpf window? want part of app window translucent, content put there should still legible. see example

please not not same changing opacity property on control, want transparency plus blur on top of primary coloured hotspots in background.enter image description here

i have darkened , blurred backgrounds before when having dialog appear on top.

the way use visualbrush blur effect create blurred visual (i blurring usercontrol not blurred before dialog appeared) , place canvas black background , reduced opacity on top darken it.

<visualbrush>     <visualbrush.visual>         <grid cliptobounds="true">             <image source="images\myimage.png">                 <image.effect>                     <blureffect radius="20"/>                 </image.effect>             </image>         </grid>     </visualbrush.visual> </visualbrush>

my code not describe want achieve, technique of using visualbrush blur effect key.

p.s. think ios version of looks awful , doubt there transparency in solution, show blurred image.
