问题 When I was used to create appx file (x64 release mode) of my project , there was only Microsoft.VCLibs.x64.14.00.appx file was created under dependency folder.

问题 I have an UWP project which I started to build using Target Version 1803. When I upgraded the solution to use Target Version 1809 my NavigationView's behaviour changed and the acrylic effect was gone. As an illustration, this is what it looked like before: And this is what it looks like now: Why does this happen? I wouldn't believe this is to match some design guidelines since Microsoft themselves still use the acrylic effect in NavigationViews in many native UWP programs. I would also like

问题 I'm making a Windows 10 Universal App and I want the user to pick a folder to save the document files for the App. The path for this folder is saved to ApplicationData.Current.RoamingSettings.Values .

问题 I am trying to start video preview capture from the camera in my UWP app but StartPreviewAsync throws an exception Sample Code: MediaCapture mc = new MediaCapture(); await mc.InitializeAsync(); await mc.StartPreviewAsync(); 回答1: This error occurs because currently StartPreviewAsync requires a sink to output frames to.

问题 I have a range of controls laid out on a canvas in my application. I am programmatically generating a point on this canvas. I wish to detect if a child of the canvas intersects with this point. I expected a hit test API to be available (wpf used to have an interface available), but it looks like all interaction seems to be through input and touch events, making it difficult to execute the query myself. It's very possible I've missed this functionality in my searches, does anyone know how to

问题 I know how to develop webpages with HTML and CSS, but I am new to the windows app development and I am trying to develop an universal windows platform (UWP) application.

问题 The MSDN documentation for the Windows.ApplicationModel.LockScreen namespace claims that "You can create an app that acts as the lock screen, allowing greater user personalization". I'm interested in creating a custom lock screen for Windows 10 Mobile.

问题 tl;dr : How do I register a Background Task without having to run the app? Long version : I want to register a Background Task to run every time the user logs in using SystemTriggerType.UserPresent . I've found information about registering the Task, but that is code that has to be executed. That would be fine if the Task only has to be executed after the app runs.
