I'm using a port of the WPF ExpanderView ( ExpanderRT ) in my UWP app to show expandable headers with items. This works fine when the app is launched for the first time and MainPage is initialized. However if I navigate to a new page and then go back to MainPage the ExpanderView looks like expanded, but not it's not showing the items.

This is the XAML of the UserControl on the MainPage ; <ListView x:Name="CategoriesListView" ScrollViewer.VerticalScrollBarVisibility="Hidden"> <ListView

Working on a Windows Phone 10 app and ran it from Visual Studio on my ARM (Lumia 950) device several times. Then an OS update came in for my 950 and it soon did a forced reboot; updating to 10.0.14393.576. I may have had one or two successful deploys/debug launches from VS to the phone after that but then this error started and I am blocked. DEP0001 : Unexpected Error: -2147009290 This comes after the app has apparently successfully deployed and is trying to launch the app. I tried several battery-pull reboots of the phone and rebooting the PC. The app is not installed on the phone (in the app

ITNOA I want to create a library, and I need to programmatically check to what capabilities enable in UWP app that use my library. I don't know how to do it?

Something like this: var doc = XDocument.Load("AppxManifest.xml", LoadOptions.None); var xname = XNamespace.Get("http://schemas.microsoft.com/appx/manifest/foundation/windows10"); var capabilitiesNode = doc.Root.Descendants(xname + "Capabilities").First(); foreach (var capability in capabilitiesNode.Descendants()) { Debug.WriteLine(capability.Name + ": " + capability

I have an uwp app running on a handheld device running windows 10. The handheld device has a barcode scanner and all input for the app is made using this.
