In C #, interfaces are different from classes (even abstract classes);

  • Interfaces can define APIs (method signatures, event declarations, property declarations) rather than an implementation (fields, method bodies, etc.).
  • you can only inherit one base class, but you can implement multiple interfaces

But they have similarities in some applications - for example, when used in an abstract implementation of a factory.
