As far as I know, the object expression does not support type attribute. We have to define concrete type:
1 2 3 4 5 6 7 8 9 10 11 12 13
open System
type ITest =
abstract Show : 'a -> unit
[<Serializable>]
type Test() =
interface ITest with
member test.Show(v) = printfn "%A" v
let test = new Test() :> ITest
test.Show(123)Bad news... Anyway thanks.

I have interface and its "anonymous" implementation (or may be better object expression). Now I would like to mark implementation with certain attributes.
[<ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)><SERVICEBEHAVIOR(INSTANCECONTEXTMODE ="InstanceContextMode.Single)">] let service = { new TaskProcessing with member gms.Post(t) = () }This code example marks field service, though.
