Can a static class be extended C#?
No. Extension methods require an instance variable (value) for an object. You can however, write a static wrapper around the ConfigurationManager interface. If you implement the wrapper, you don’t need an extension method since you can just add the method directly.
Can you extend a static class?
extending static classes is allowed, since its members are not necessarily static. the static modifier can only be used on nested classes because it can only be used on class members (and only nested classes can be class members).
How do you extend a class in C#?
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 extension methods extend non static classes?
Extension method are to extend the class, not give you full control over the innards of it. @Pete Static Functions don’t require an instance of a non-static class to exist.
Can you inherit from a static class in C#?

Can a class be static in C#?

Can we override static method C#?
Well You can’t override a static method. A static method can’t be virtual, since it’s not related to an instance of the class. The “overridden” method in the derived class is actually a new method, unrelated to the one defined in the base class (hence the new keyword).
