Usage in FSharp

NullValueHandling

By default DefaultValueHandling is Ignore. Since F# Option.None is treated as null, it will be ignored by default. To include Option.None use VerifierSettings.AddExtraSettings at module startup:

VerifierSettings.AddExtraSettings(fun settings -> settings.NullValueHandling <- NullValueHandling.Include)

Async Qwerks

F# does not respect implicit operator conversion. SettingsTask uses implicit operator conversion to provide a fluent api in combination with an instance that can be awaited. As such SettingsTask.ToTask() needs to be awaited when used inside F#.

[<Fact>]
let MyTest () =
     Verifier.Verify(15).ToTask() |> Async.AwaitTask
