Enum support
By default enums are represented as integer values.
type PostStatus =
| New = 0
| Published = 1
| Archived = 2
If you prefer more descriptive values in a database, you can override them using EnumValueAttribute:
type PostStatus =
| [<EnumValue("N")>] New = 0
| [<EnumValue("P")>] Published = 1
| [<EnumValue("A")>] Archived = 2
Arguments of EnumValueAttribute can be any values, that can be written do a database (integers, strings, etc.).
