How to query DTED offline using ArcGIS .Net SDK?

Our application needs to do some elevation calculations (and is not connected to the internet), as a result we need to determine the highest elevation for a given polygon. How can we query DTED offline using ArcGIS .Net SDK?

 

Option 1 - Use Esri.ArcGISRuntime.Controls.FileElevationSource

So in order to use FileElevationSource it turns out it must be associated with a SceneView. We were only using a MapView so I added in a SceneVeiw and associated the FileElevationSource

sceneView.Scene.Surface.Add(elevationSource);W

When I tired to access the elevation source I get an AccessViolation

elevationSource.GetElevationAsync(location as MapPoint).Result

Option 2 - Some how use LocalServer

The doco states that ArcGIS Runtime LocalServer support a number of Raster formats including DTED.

Local Server raster support—ArcGIS Runtime SDK for .NET | ArcGIS for Developers 

So I use ArcMap to create a map package file with the DTED files within but have no idea how to use Local Sever to query the package file 

 

Ultimately we want to:

1) Load a number of DTED files  

2) Query for a given lat/lon what the elevation is at that point

 

Any help would be greatly appreciated!

 

Note we are using .Net Runtime SDK v10.2.7
