See Roslyn-Detected C# Warning Classes for more information.
Interfaces define members that provide a behavior or usage contract. The functionality that is described by the interface can be adopted by any type, regardless of where the type appears in the inheritance hierarchy. A type implements an interface by providing implementations for the members of the interface. An empty interface does not define any members; therefore, it does not define a contract that can be implemented.
This check corresponds to Roslyn rule CA1040. For full rule details, see the Microsoft website: CA1040.
