How to define a enumeration without define values?
f#

Well, I have the following enumeration define:

[<Flags>]
type MOUSEEVENTF =
| MOVE = 0x1
| LEFTDOWN = 0x2
| LEFTUP = 0x4
| RIGHTDOWN = 0x8
| RIGHTUP = 0x10
| MIDDLEDOWN = 0x20
| MIDDLEUP = 0x40
| XDOWN = 0x80
| XUP = 0x100

and it compiled to .Net's enum, but if I try to remove the value definitions:

[<Flags>]
type MOUSEEVENTF =
| MOVE
| LEFTDOWN
| LEFTUP
| RIGHTDOWN
| RIGHTUP
| MIDDLEDOWN
| MIDDLEUP
| XDOWN
| XUP

then it will compile to class and static fields, how can I make it to compile to enum please?

.

If you want it compiled to a .NET enum, then you must specify the values. Otherwise it is an F# discriminated union. See also

If you could just define the first value and have the rest of them automatically assigned, it would be handy when you're defining enums to be used from other .NET languages.
