i just have a model >

    public class HomeModel
    {
        public string Name { get; set; }
        public string Email { get; set; }

    }

    public class HomeModel
    {
        public string Name { get; set; }
        public string Email { get; set; }

    }

that's called on the main controller >

        public IActionResult Index()
        {
            HomeModel home = new HomeModel();
            home.Email = "nrochalacerda@gmail.com";
            home.Name= "Nicolas Rocha Lacerda";
            return View(home);
        }

        public IActionResult Index()
        {
            HomeModel home = new HomeModel();
            home.Email = "nrochalacerda@gmail.com";
            home.Name= "Nicolas Rocha Lacerda";
            return View(home);
        }

this is the code from _Layout.cshtml, right? You inject model in the controller page, which is located in the Views/Home/Index.cshtml

exactly how can i do it ?

добряк•16mo ago

all you need is to call the model in Views/Home/Index.cshtml instead of _Layout.cshtml and this will work.

You can read about layout here: https://learn.microsoft.com/en-us/aspnet/core/mvc/views/layout?view=aspnetcore-7.0
