Michael,

>Having just purchased MM.Net, I've been going through the jump start guide to build a windows application. Everything works well up until step 13: Enhancing the DataGrids. When I launch the collection editor, the MappingName comes up empty. What am I missing?

This is standard behavior in VS 2003 when you're not hard-coding your data access in the UI. You just need to manually enter the information in the builder.

Regards,
