Comments: I just updated with entire code snippet from test application I used to recreate the issue. I don't know why I didn't include entire snippet before. I used a WPF application in VS 2013. I used NuGet to load libraries - it loaded V1.7. The features and the DataTable fields all look great before SaveAs(). I added another attachment showing what the result looks like in ESRI Explorer and what they look like in VS debugger just before FeatureSet.SaveAs().
