问题 I am using the windows phone emulator. I wrote a very simple program: draw a marker on the map when the user tap the map once. Then I used map_tap event, and get the tapped location as follows, private void map_Tap(object sender, System.Windows.Input.GestureEventArgs e) { Point p = e.GetPosition(null); GeoCoordinate s = map.ConvertViewportPointToGeoCoordinate(p); Ellipse myCircle = new Ellipse(); myCircle.Fill = new SolidColorBrush(Colors.Blue); myCircle.Height = 20; myCircle.Width = 20;

问题 I am developing a Windows phone app, where I have a viewportcontroller, that enables me to zoom in and out on content. I want to center the zoom at the point where I zoom. Which I can do with Viewportcontroller.SetViewportOrigin() But this makes the viewportcontroller jump to the origin I set. Which does not look very nice. I therefore would like to create a storyboard that changes the origin gradually as the zooming occurs. I therefore would like to ask how I should do this with a property

问题 I have an app which adds a secondary tile to the user's homescreen. I would like to make that tile wide by default. However, despite enabling it is a wide tile it is never wide when initially added, which forces the user to resize it manually. I would really like to avoid making the user resize the tile manually, and there is a sample application which definitely adds a wide tile with the press of a button. Unfortunately the code they use to do so is precompiled and obscured. I know it MUST
