In previous versions (100.1, 100.2), the following code would put a copy of the displayed map image on the Clipboard:
var bv = _mapView;
RenderTargetBitmap rtb = new RenderTargetBitmap((int)bv.ActualWidth, (int)bv.ActualHeight, 96, 96, System.Windows.Media.PixelFormats.Pbgra32);
Now, however, the map portion is rendered as black (although the credits line at the bottom "Esri, HERE, NGA, USGS" still shows).
Is there a way to get this to work?
