问题 I am trying to get a BLE advertisement callback from a .NET Windows desktop application. I am able to call into the APIs, however the Received event is never called from the OS in a WPF or Command line application. I do get events when the code is called from a Unit Test in VS2015, or universal Windows app. However, I need to do other things not available in universal Windows. Here is the code: using Windows.Devices.Bluetooth.Advertisement; public static void ScanForAdvertisments() { mWatcher

问题 I am new to T10 and trying to learn it. This is a follow-up to Template 10 Multiple Windows In 'regular' (meaning non-Template10) UWP app I've learned to do something like this (as a short example) in order to support multiple views: public App() { InitializeComponent(); Suspending += OnSuspending; } readonly List<CoreDispatcher> _dispatchers = new List<CoreDispatcher>(); protected override async void OnLaunched(LaunchActivatedEventArgs e) { Frame rootFrame = Window.Current.Content as Frame;

问题 We have a Xamarin Forms project which shall run on Android, iOS and UWP. On Android you have a number of different images in different folder to support a vast number of different screens (and PPIs) on iOS you have a similar system (@2x, @3x etc.). I can't for the life of me find how to achive something similar for UWP. When I run the project on a Windows tablet with a recommended scaling of 150 % or 200 % all the images are also scaled up, which results in a blurry image. I can't find any

问题 What icon sizes should I use for the app bar/command bar? I couldn't find something in Guidelines for tile and icon assets or in UWP App Visual Assets. Other names: navigation bar (iOS), app bar/action bar (Android), toolbar (Xamarin.Forms) 回答1: Image size The default icon size should be 20 pixels for app bar image at 100% scaling, but you should also provide additional image assets to ensure it looks great on all screens: appbaricon.scale-100.png - 20 px appbaricon.scale-125.png - 25 px

问题 So HoloLens is stupid in that it only recognizes one FilePicker at a time (no matter how many may be installed). I don't believe the developers are going to try making multiple filepickers work. So, I'm trying to figure out my own filepicker in an attempt to be a proxy-select for other filepickers. In essence, I want to make a filepicker chooser that appears as a typical filepicker (if that makes sense). Trouble is, it doesn't appear possible to get a list of pickers installed! Am I

问题 There's a new RatingControl in UWP that allows you to show ratings as a series of stars. I was wondering how I can change the size of the stars and also the spacing between them. FontSize does not work like it did on the Telerik version for UWP. I hope this is possible without restyling the whole control. For example, Microsoft explicitly states "Spacing customization" as a feature: The rating control has many additional features which can be used. Details for using these features can be
