Lurking beneath the surface is an unsettling feeling that all of this is a little to automagic and that if I break something I may not be abl...
I have a DataForm bound to the selectedItem of a listbox. Before the user selects an item in the listbox the DataForm is blank, by that I mean there is absolutely nothing displayed, no labels, textboxes or anything. Once the user selects an item in the listbox then then the form renders data as expected. How do I get the form to displ...

Depending on user selection, a DataTable is filled by one of the TableAdapters and passed to another form for display/Edit in a DataGridView.

Well, I am not alone who is being sick of magical strings which are constantly used just to do data binding -- see: http://stackoverflow.com/questions/1329138/how-to-make-databinding-type-safe-and-support-refactoring However I am concerned with performance of this solution and much more typing -- each time you would like to use nameof ...

Do I have to duplicate each Model class as some sort of DTO and expose those DTOs from the ViewModel ? I understand the theoretical value of having the View "not know" about the Model, but the reality is that (if I don't expose the M...
