The NuGet ArcGISRuntime is V10.2.7.1234 and the NuGet ArcGISRuntime.WPF is v100.0.0. In Author, edit, and save maps to your portal—ArcGIS Runtime SDK for .NET | ArcGIS for Developers, it seems that both have to be loaded. Is that OK? Elsewhere I've seen discussions that indicate ArcGISRuntime.WPF is a update to V10.2.7.1234. Is that right?
