Ok, this is one of those mistakes. I simply forgot to connect the
mainTable outlet from my ApplicationController to the NSTableView.

I was able to get data loaded to the NSTableView from its

lines of code my application quits.
//note - mainTable is the NSTableView, mds is the datasource to be set
mainTable.DataSource = mds;
mainTable.ReloadData();
After the application quits, it then shows the following exception -
