问题 I'm trying to use Entity Framework Core with UWP. I found this sample from Microsoft and got it to work. In this sample, the object models are in a .Net Standard class library. However, for the project I'm working on, I need to be able to use MVVM Light's RaisePropertyChanged method in the setters of my object models. The issue I'm running into is that MVVM Light is apparently not compatible with .NET Standard 2.0, only 1.0. MVVM Light does seem to install correctly to the class library, but

问题 I have been trying to install the HoloLens emulator with no success. I have installed and uninstalled the windows SDK, Installed and enabled visual studios as the external editor and installed the UWP tools when I installed VS 2019. I have Windows 10 Pro installed and Unity 2018.4 . I have installed the Windows 10 SDK (10.0.17763.0) through the VS Installer. When I run the HoloLens Installer I get these log errors. ValidateVisualStudioVersion: Visual Studio 2017 meets the minimum version

问题 Environment : Windows 10 Pro - v1903 , VS2019 - v16.6.2 Using this sample code from Microsoft docs, I was able to create a tile - with a text message - as shown below. But I would like to display 3 different static text messages in a certain interval. Question : In the above tile example, how can we repeat the display of 3 different static text messages via a local tile notification. For example: Every 10 minutes: Display This is message 1 in the first interval, This is message 2 during next

问题 For personal needs, for the Xamarin.Forms.Map control, I need to create a CustomPin extension. UWP part (PCL project) I create a MapIcon like it: nativeMap.MapElements.Add(new MapIcon() { Title = pin.Name, Image = RandomAccessStreamReference.CreateFromUri(new Uri("ms-appx:///Assets/Pin/customicon.png")), Location = new Geopoint(new BasicGeoposition() { Latitude = pin.Position.Latitude, Longitude = pin.Position.Longitude }), NormalizedAnchorPoint = new Windows.Foundation.Point(0.5, 1.0) });

问题 I am using a slider to control the position of a playing MediaElement. I have implemented the ValueChanged event to synchronize the position and the value of slider. So when I am dragging on the Thumb, the position of MediaElement also changes. However, this creates bad user experience. The ideal case should be like, after user finishes sliding, MediaElement jumps to that final position. So I am looking for events/handlers like AfterSliding. I have seen solutions like using
