What reference to add for VBIDE

I have a VB .Net Project I am working on. This weekend when I copied the project to my computer at home to work on it. A reference to named VBIDE in the Solution Explorer was broken. I don't remember what this reference does or if it's a standard reference added to every VB project you create.

Can someone tell me what reference I need to actually add to the project to make this error go away. Does anyone know what this reference actually does?

Thank you :)

Nobody knows what reference this is?

I think you'll find it has something to do with Microsoft Office and VBA. I added a reference to the Excel object library in a project of mine and got new references to Excel, Microsoft.Office.Core and VBIDE. The description in the properties window reads "Microsoft Visual Basic for Applications Extensibility 5.3".

OK I added a reference to Excel in my project, however I decided to start using a CSV file which is faster to create for what I need to do. It should be safe to remove this reference and still have my project work correct?

Without accepting any liability for mishap, absolutely safe :D
