问题 I have a Xamarin solution with a UWP project in it. I cannot understand how to copy a file that is in my VS project to the UWP LocalFolder. I've tried fiddling with the file's Build Action (Compile, Content, Embedded Resource, AdditionalFiles) and I've tried to manually create this location.

问题 I'm an Android developer trying to learn UWP development, and stuck on this simple need. I have 3 pages and want to make a ProgressRing accessible to all 3 pages, so when I'm doing an async task I can pop up the ProgressRing modal. I don't want to have ProgressRing code in each page.

问题 I've created an universal app that connects to a WCF webservice at intranet, an it's working just fine, since the address of the service's host is known.

问题 A couple of questions about CameraCaptureUI. 1) Can I control the size/placement of the popup? It pops up very small on my Win10 tablet and it's really annoying to enlarge it each time the app needs to take a photo! 2) I am trying to create photos that are equivalent in quality to the built-in camera app, but I had a lot of trouble with this. Only by playing around with the croppedSizeInPixels could I get anything larger that seemed decent quality. Can someone explain why this helped and if
