Answer 1

Now in F# 4.6 (preview) we have Anonymous Records

So we can have this code syntax:

let AwesomeAnonymous = {|  ID = Guid.NewGuid()
                           Name = "F#"
                        |}

AwesomeAnonymous.Name |> Debug.WriteLine

It is also supported on the Visual Studio Intellisense:

So that code could be like this:

routes.MapRoute(
    "Default", // Route name
    "{controller}/{action}/{id}", // URL with parameters
    {| controller = "Home"; action = "Index"; id = UrlParameter.Optional |} // Parameter defaults
  )
