title: ExcelDNA / Managed XLL / Excel Interop
body: <p>I find it quite unbelieavble that the interop API is such a mess</p>
  
  <p>A lot of methods have no comments on and seems to have been done very poorly</p>
  
  <p>Has anyone else experienced the same and if so what library do you use to control Exel from C#?</p>
