Based heavily on a project by Warren Buckley, I am trying to write a new membership controller in Umbraco 7.5.2.

However, my first challenge is that I cannot get the remote validation to work.

The error message states (sorry about the norwegian in between there):

No url for remote validation could be found.

Beskrivelse: Det oppstod et ubehandlet unntak under kjøring av gjeldende webforespørsel. Gå gjennom stakksporingen hvis du vil ha mer informasjon om feilen og hvor den oppstod i koden. 

Unntaksdetaljer: System.InvalidOperationException: No url for remote validation could be found.

This is my model:

 public class RegisterViewModel
{
    [Required(ErrorMessage = "Please enter yourname")]
    public string Name { get; set; }

    [DisplayName("Email address")]
    [Required(ErrorMessage = "Please enter your email address")]
    [EmailAddress(ErrorMessage = "Please enter a valid email address")]
    [Remote("CheckEmailIsUsed", "MyMembersController", "MyMembers" ,ErrorMessage = "The email address has already been registered")]
    public string EmailAddress { get; set; }

    [UIHint("Password")]
    [Required(ErrorMessage = "Please enter your password")]
    public string Password { get; set; }

    [UIHint("Password")]
    [DisplayName("Confirm Password")]
    [Required(ErrorMessage = "Please enter your password")]
    [System.ComponentModel.DataAnnotations.Compare("Password", ErrorMessage = "Your passwords do not match")]
    public string ConfirmPassword { get; set; }
}

This is my controller:

  [PluginController("MyMembers")]
public class MyMembersController : SurfaceController
{
(...)

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult HandleMemberRegister(RegisterViewModel model)
    {
        if (!ModelState.IsValid)
        {
            return PartialView("Register", model);
        }

        var verifyEmailGuid = Guid.NewGuid();

        //Model valid let's create the member
        try
        {
            // Create new member
            var newMember = ApplicationContext.Services.MemberService.CreateMember(model.EmailAddress, model.EmailAddress, model.Name, "Member");
            ApplicationContext.Services.MemberService.Save(newMember);

            // Save the password
            ApplicationContext.Services.MemberService.SavePassword(newMember, model.Password);

            // Set hasVerifiedEmail to false
            newMember.SetValue("hasVerifiedEmail", false);

            // Set GUID to user for email verification
            newMember.SetValue("verifyEmailGuid", verifyEmailGuid.ToString());

            // Save the new member
            ApplicationContext.Services.MemberService.Save(newMember);
        }
        catch (Exception ex)
        {
            throw ex;
        }

        //Send out verification email, with GUID in it
        var emailToSend = new StringBuilder();
        emailToSend.AppendFormat("<p>Welcome to our site. Please click this link to verify your email.</p>");
        emailToSend.AppendFormat("<p><a href='test.com/{0}>test.com/{0}</a></p>", verifyEmailGuid);

        // Send password in email
        SendEmail(adminEmail, model.EmailAddress, "Verify your email", emailToSend.ToString());

        //Return  view...
        return PartialView("Register", new RegisterViewModel());
    }

And the view:

 @inherits Umbraco.Web.Macros.PartialViewMacroPage


@using System.Web.Mvc.Html
@using ClientDependency.Core.Mvc
@using Umbraco.Web
@using losol.CMS.Controllers



@{
    var regModel = new losol.CMS.Models.RegisterViewModel();

    Html.EnableClientValidation();
    Html.EnableUnobtrusiveJavaScript();
    Html.RequiresJs("/umbraco_client/ui/jquery.js");
    Html.RequiresJs("/umbraco_client/Application/JQuery/jquery.validate.min.js");
    Html.RequiresJs("/umbraco_client/Application/JQuery/jquery.validate.unobtrusive.min.js");

    var success = TempData["FormSuccess"] != null;
}

@*NOTE: This RenderJsHere code should be put on your main template page where the rest of your script tags are placed*@
@Html.RenderJsHere()

@if (success) 
{ 
    @* This message will show if RedirectOnSucces is set to false (default) *@
    <p>Registration succeeeded.</p>
}
else
{
    using (Html.BeginUmbracoForm<MyMembersController>("HandleMemberRegister"))
    {
        <fieldset>
            <legend>Register Member</legend>

            @Html.ValidationSummary("registerModel", true)

            @Html.ValidationMessageFor(m => regModel.Password)
            <br />
