Can you update ArcGISRuntime.Toolkit and LocalServices to v.200 ASAP ?

Question

ArcGISRUntime for .NET has been updated to 200.0.0.   I'm using the Toolkit for loading a base map.   Unfortunately under 200 for ArcGISRUntime.WPF, BasemapGallery goes into an hour glass forever.

For LocalServices (100.15) running gpkx under ArcGISRUntime 200, it generates many exceptions like

Exception thrown: 'System.Net.WebException' in System.dll

Exception thrown: 'System.ObjectDisposedException' in System.dll

Exception thrown: 'System.InvalidOperationException' in System.dll

Exception thrown: 'System.ObjectDisposedException' in System.dll

Here is what happens.  Do you need more?   I was running the Simple Contour gpkx in WPF application build for NetFramework 4.8.

I enabled LocalServer debug option also.

When Exception (The request was aborted: The request was cancelled) is triggered, it is looking for _ConnectionStream.cs file.

The call stack:

I found the cause.

Previously GeoModel did not have to be set.  It turned out that under v.200, it is required and you can use ElementName=MyMapView, Path=Map works.  When I make BasemapGallery starts as Visibility="Collapsed" and modify it to Visibility=Visible" later by ICommand, it does hourglass and does not come back.  Is there a way to diagnose why it does not come back?

Is there a reason why SceneView is tied to BasemapGallery?  My code is using MapView for BasemapGallery.  Is it possible to use MapView?  Is there any way for MapView to use BasemapGallery?
