I´m using ArcGIS Runtime for WPF in my .NET application (SDK WPK 10.2), and when I try to load an ESRI.ArcGIS.Client.Toolkit.DataSources.OpenStreetMapLayer as a basemap in my MapControl (with MapStyle=CycleMap), it does successfully but a "watermark" API Key required is displayed.
Is there any way to remove this annoying label ?
