So I’m doing new work on a SharePoint feature that’s already deployed, so naturally, I have to do some upgrade actions to deploy some new fields to a content type. There are a few fields to add, and since the AddContentType field doesn’t have any naming elements, I decide to throw in some comments before each entry, so I know which field is which and I make sure I haven’t forgotten any. Everything compiles fine and Update-SPSolution works fine. Then, I try to run my upgrade and I get the following error:
Really, SharePoint? You can clearly see that it’s a comment, and yet you still just barf on it rather than just ignoring it. WHY!?
