My plan is to populate the database programatically; however, the INSERT command does not seem to be working correctly. I can see that the data actually gets added to the database when I add it and iterate over it programatically (using SqlCeCommand ...Show All

This controls the scope of elements read from an XML file when calling ReadXml and the file is read correctly with appropriate rows populated. Now, if I turn around and call Write ...Show All
