Why c# value types extend Object? my take

It's always been a puzzle to me why C# creators made this decision --

Q: why are all value types (including enums, structs and simple ints/floats etc) designed to be subtypes of System.Object. I don't know any language (python?) making a primitive data type extend a reference type. Bold departure from tradition?
%%A: perhaps they want Object params to accept value type arguments?

Q: what "assets" do the int type (and other value types) inherit from Object supertype?
%%A: I only know ToString(), GetType(), GetHashCode(), Equals() etc. Obviously Int32 won't inherit actual Implementation of GetType(), but it does inherit the calling Signature, so this GetType() method can be called on an Int32 instance.
