Can we write extension method for interface?
You can use extension methods to extend a class or interface, but not to override them. An extension method with the same name and signature as an interface or class method will never be called. At compile time, extension methods always have lower priority than instance methods defined in the type itself.
Can you add methods to an interface?
Like a class, an interface can have methods and variables, but the methods declared in an interface are by default abstract (only method signature, no body). If a class implements an interface and does not provide method bodies for all functions specified in the interface, then the class must be declared abstract.
