David Abitbol's questions

Eu tenho a seguinte página .NET Razor, não importa o que eu tente, nenhuma das propriedades parece vincular POSTe são todas nulas.

Quando olho para o objeto postado, todas as propriedades são nulas.

Auxiliares de tags estão incluídos

@page
@model AppointmentModel
@{
    ViewBag.Title = "Rendez-Vous";
    ViewBag.pTitle = "Rendez-Vous";
    ViewBag.pageTitle = "Accueil";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
...
                <form id="formSubmit" method="post">
                    <div class="row">

Tentei criar uma classe separada e passei quase uma hora depurando. Tentei colocar no corpo, nada funciona. Estou no .NET 7.
