Creating instance of interface in C#

Question

I\'m working with MS Excel interop in C# and I don\'t understand how this particular line of code works:

var excel = new Microsoft.Office.Interop.Excel.Appli         


        

Answer 1

Actually code that you mentioned created instance of the ApplicationClass class and that is what CoClass attribute does.

See this answer for details: How does the C# compiler detect COM types?
