Hi,
Instead of using Package Map GP Tool to create the .mpk another workflow would be be the following:
> Open up the .mxd containing your File Geodatabase or a reference to your File Geodatabase in ArcMap.
> Navigate to File > Share As > Map Package and make sure "Support ArcGIS Runtime" is checked
> Check on "Reference all data" if you want to create a map package that points to the data needed rather than copying the data.
> The .mpk can then be consumed in your WPF application.

what would be the best way to expose a feature class which is stored in a (file) geodatabase in a WPF ESRI Map Control as a Feature Layer using ArcGIS Runtime. Currently we are using a empty map file (.mxd), add a reference to the feature class and save it as a new map file (.mxd), convert the .mxd to a map package with runtime support (.mpk) and then consume it as a LocalArcGISFeatureLayer. Would you agree that this is the best and preferred ESRI way?
