Excel _WorkBook vs. Excel.Workbook

[Jim Heavey]

What is the difference between these two objects and which should I be using
to create an Excel worrkbook in code?

Is there some reason I should create a reference to the
Microsoft.Office.Core vs. Microsoft.Excel.10.Objects.Library? I suppose the
office give me access to the whole suite of application where excel is excel.
So if I think I might need the others, then include the office reference and
not the excel? The coding is going to be the same in both cases...right
(assuming the same version of Excel)?

Thanks in advance for your assistance

You shouldn't really be instantiating either of those objects from ASP.NET
(even though I think they are really two different pointers to the same
object.)
Excel wasn't designed to be used as a server component, so you're inviting
problems.
