I was going to teach myself how to make a table view app, so I went the the Xamarin recipe Storyboard a Tableview. Seemed like a good place to start.
http://docs.xamarin.com/recipes/ios/general/storyboard/storyboard_a_tableview
Down in the list there is a line that reads "The example code includes a TableSource and TableItem class in the Code folder, plus some images. Add these to your project:".
So I click on the link at the top of the page for Storyboard_a_Table.zip and get a 404 error. Right-click the same link, just to make sure, and Save As. Not a valid .zip file. Stuck.
