Code

let blah =
    Mock().Returns(fun _ ->
                {
                    dasdasdsadsadsadsa = ""
                    Sdadsadasdasdas =  "sdsadsadasdsa"
                })

Error

let blah =
    Mock ()
        .Returns(fun _ ->
            {
                dasdasdsadsadsadsa = ""
                Sdadsadasdasdas = "sdsadsadasdsa"
            })
