"Cannot create an instance of the abstract class or interface" C# error message -

-

i changed base class abstract project , i'm receiving following error:

cannot create instance of abstract class or interface

am receiving error because naming new instance of abstract class not allowed?

newplane = new airplane_abstract(name, position);

you can't create instance of abstract class. think of interface may contain implementation logic well. expect happen if called abstract instance method no definition?
