Trying to use the Microsoft.Office.Tools.Excel namespace by referencing the
dll made available by VSTO with the same name. (You can get it as a
redistributable package as well).

Problem is... Intellisense seem to read and present the methods and
properties available in Microsoft.Office.Interop.Excel namespace without me
even having a reference to that COM dll.

I can't make use of that dll so I wont be able to add a reference to it in
my project. Shouldn't the managed dll (Microsoft.Office.Tools.Excel) have all
the methods I need?

Thanks!
