Answer 1

Yes, the literal 0 is implicitly convertible to any enum type and represents the default value for that type. According to the C# language specification, in particular section 1.10 on enums:

The default value of any enum type is the integral value zero converted to the enum type. In cases where variables are automatically initialized to a default value, this is the value given to variables of enum types. In order for the default value of an enum type to be easily available, the literal 0 implicitly converts to any enum type. For the default value of an enum type to be easily available, the literal 0 implicitly converts to any enum type.
