I copied code from the "Add Shapefiles and Rasters" example into my project. When I try to add a raster layer, I get a message box that says "This ArcGIS Runtime application is running using a development license. This license is valid for development and testing only". Also, my raster image does not show up over the basemap (but it does when I run the sample).
My license string (in Application.xaml.cs) is set up for Development,C#,Standard, and no extensions.
Any ideas?
