How declare Xamarin.Forms.Dependency with F#?

Question

I'm porting from C# this code:

using MicroBlink;

[assembly: Xamarin.Forms.Dependency (typeof (BlinkIDImplementation))]
namespace BlinkIDApp.iOS
{
    public class BlinkIDImplementation : IBlinkID
    {
        CustomDelegate customDelegate;
        bool isFrontCamera;

        public BlinkIDImplementation ()
        {
            customDelegate = new CustomDelegate ();

            BlinkID.Instance ().LicenseKey = "MZEFTUGV-******";
            BlinkID.Instance ().Delegate = customDelegate;
            isFrontCamera = false;
        }
    }
}

But then, this part can't see how write it in F#:

[assembly: Xamarin.Forms.Dependency (typeof (BlinkIDImplementation))]

I try:

[<assembly: Xamarin.Forms.Dependency (typeof (BlinkIDImplementation))>]

And I get:

Error FS0841: This attribute is not valid for use on this language element. Assembly attributes should be attached to a 'do ()' declaration, if necessary within an F# module.

Just write this fragment:

[<assembly: ...>]
do ()

I try: `[]` and get error. Also: `do (typeof BlinkIDImplementation)` neither work. – mamcx Nov 06 '17 at 17:02
Did you try this? `[]` `do ()` – Igor Bespalchuk Nov 07 '17 at 19:08
Yes. It still not work. Get error FS0001 `[] do (typeof BlinkIDImplementation)` – mamcx Nov 07 '17 at 21:13
Why you did not try _exactly_ that code, that i wrote? Remove "typeof BlinkIDImplementation" from your last comment. Just "do()". – Igor Bespalchuk Nov 09 '17 at 06:53
