Just a quick note about an odd quirk I found today. While modifying an Item, you have to put it into Edit mode (using item.Editing.BeginEdit() ), however, if you change the Template of the Item (using item.ChangeTemplate(<newTemplate>) ), the next change you try to make will fail, because changing the Template pulls the Item out of Edit mode.

The solution? ChangeTemplate doesn’t require the item to be in edit mode to run, so simply move it above the BeginEdit call, and you’re good to go. Here’s the fixed version of the above code:
