I want to use HierarchyNode class which is in the Microsoft.VisualStudio.Package namespace and the assembly is MPF.Project.NonShipping.dll. There was no assembly on the .net reference or on the COM. I searched for the file, but it was not on the machine. I also tried to google the dll if we could download it, but there was no link, whatsoever about the download.
I am using VS 2008 sp1 by the way. Thanks in advance.
