Actionresult and async method Using Fastmapper, Typeadpter Error

Question

I have the following problem with Fastmapper. When implementing an Actionresult async when using Typeadapt it cannot perform the asynchronous conversion, would anyone know how to do the conversion with Fastmapper? Remembering, when I do the conversion by hand and or without async the same works normally. Code presenting the problem:

// GET: Credito/Details/5
public async Task<ActionResult> Details(int? id)
{
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    var creditoTabela = db.Creditos.FindAsync(id);

    CreditoViewModel creditoTela = await TypeAdapter.Adapt<CreditoModel, CreditoViewModel> (creditoTabela);


    if (creditoTela == null)
    {
        return HttpNotFound();
    }
    return View(creditoTela);
}

Error message:

Without using Fastmapper works normally, my problem is how to use Fastmapper with Async? I have to implement something in the Model part to make it work?

    // GET: Credito/Details/5
    public async Task<ActionResult> Details(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        var creditoTabela = db.Creditos.Find(id);

        CreditoViewModel creditoTela = new CreditoViewModel() {
            Codigo = creditoTabela.Codigo,
            Descricao = creditoTabela.Descricao,
            Nome = creditoTabela.Nome,
            Imagem = creditoTabela.Imagem
    };


        if (creditoTela == null)
        {
            return HttpNotFound();
        }
        return View(creditoTela);
    }

For the home page documentation, Adapt is not asynchronous.

Switch to:

// GET: Credito/Details/5
public async Task<ActionResult> Details(int? id)
{
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    var creditoTabela = await db.Creditos.FindAsync(id);

    CreditoViewModel creditoTela = TypeAdapter.Adapt<CreditoModel, CreditoViewModel> (creditoTabela);

    if (creditoTela == null)
    {
        return HttpNotFound();
    }
    return View(creditoTela);
}

You already use an asynchronous method within this Action. The Fastmapper method need not be either.
