When enum case marked with [<Obsolete>], compiler doesn't give warning.
Even with [<Obsolete("Hello, world!", true)>] it still compiles.
Repro steps
-
Make enum
-
Tag some case with [<Obsolete>] attribute
-
Try use it somewhere
Example script:
open System
type MyDU =
| Case1
| [<Obsolete>] Case2
let xx = MyDU.Case2 // <- gives warning
type MyEnum =
| Case3 = 0
| [<Obsolete>] Case4 = 1
let yy = MyEnum.Case4 // <- no warning
printfn "%A %A" xx yy Expected behavior
When enum case is marked as obsolete, compiler should give warning or error depending on Obsolete attribute configuration
Actual behavior
No compiler warning or error
