Data binding in ASP.NET MVC Core - asp.net-mvc

Question

I am trying to read from HTML form some data. I succeeded to do it in ASP.NET MVC but not in ASP.NET MVC CORE.
Any help will be appreciated!

This CSHTML code on ASP.NET MVC (worked fine):
#using (Html.BeginForm("Login", "Account")){
<form class="form-group" action="Login" method="post">
<input name="AccountAddressTxt" type="text" class="form-control" required="required" id="AccountAddress" placeholder="Enter Your Account Address" style="width:50%" onclick="SetOx()">
<br />
<input name="AccountPasswordTxt" type="password" class="form-control" required="required" id="AccountprivateKey" placeholder="Enter Your Account Private Key" style="width:50%">
<input id="loginBtn" type="submit" class="btn btn-success" style="width:50% ;" value=" Login">
</form>
And the data binding (worked fine):
namespace RealEstate-Web_app.ModelsBinders
{
public class AccountBinder: IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
HttpContextBase objContext = controllerContext.HttpContext;
String _accountAddress = objContext.Request.Form["AccountAddressTxt"];
String _accountPassword = objContext.Request.Form["AccountPasswordTxt"];
Account obj = new Account()
{
AccountAddress = _accountAddress;
AccountPassword = _accountPassword;
};
return obj;
}
}
}
Right into the controller (worked fine):
[HttpPost]
public IActionResult Login([ModelBinder(typeof(AccountBinder))] Account acc)
{
return View("Login", acc);
}
But in ASP.NET MVC CORE I am getting another method with no idea what to do:
...
using Microsoft.AspNetCore.Mvc.ModelBinding;
namespace RealEstate_Web_app.ModelBinders
{
public class AccountBinder : IModelBinder
{
public Task BindModelAsync(ModelBindingContext bindingContext)
{
//What am I suppose to do here?
}
}
}

Follow a similar format to what was done previously. There are some changes in the new version that should be noted.
namespace RealEstate_Web_app.ModelBinders {
public class AccountBinder : IModelBinder {
public Task BindModelAsync(ModelBindingContext bindingContext) {
if (bindingContext == null) {
throw new ArgumentNullException(nameof(bindingContext));
}
var modelName = bindingContext.ModelName;
HttpContext httpContext = bindingContext.HttpContext;
String _accountAddress = httpContext.Request.Form["AccountAddressTxt"];
String _accountPassword = httpContext.Request.Form["AccountPasswordTxt"];
Account model = new Account() {
AccountAddress = _accountAddress;
AccountPassword = _accountPassword;
};
//TODO: validate and update model state if not valid
//...
bindingContext.Result = ModelBindingResult.Success(model);
return Task.CompletedTask;
}
}
}
