I am trying to figure out how to have a transparent background on the app, that lets the user see behind it. I've tried to change background
and opacity
parameters in xaml
file, but nothing changed.
I have set a transparent image in background also
<Page.Background>
<ImageBrush Stretch="Fill" ImageSource="Assets/fond.png"/>
</Page.Background>
But it doesn't work
Does anyone know how to perform this?
tl;dr https://docs.microsoft.com/en-us/windows/uwp/design/style/acrylic
You will be able to do it after the update of Windows 10 that is coming.
Here: https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/8232264-enable-blur-and-transparency-xaml-effects-to-allow?tracking_code=8e9425d1ccc153460b32b85ed3253c90
And the github: https://github.com/Microsoft/WindowsUIDevLabs/tree/master/SampleGallery/Samples/SDK%20Insider/BlurPlayground
Maybe it's not the straight "see through", but I think it's what you would like to have.
EDIT: I think it is available in the SDK Preview, but I'm not sure because I didn't try it.
Info about Anniversary SDK Preview https://developer.microsoft.com/en-us/windows/downloads/windows-10-developer-preview
SDK is here https://insider.windows.com/
UPDATE:
I've just noticed prelease of CreateHostBackdropBrush() function in Compositor class. https://docs.microsoft.com/en-us/uwp/api/windows.ui.composition.compositor
UPDATE:
In Fall Creators Update it's even available as XAML code that's very fast and easy to write.

I think the root cause that it is not possible to make your app background full transparent. I believe when you implement some image as background it will be possible to do.
