Hi, I´m new to MVC, and I have followed a tutorial for building a contact form page but get this error message: namespace name 'Models' does not exist

Gets a lot of code, but I do not know what is relevant and not.

Controller

namespace test.Controllers {
    public class ContactSurfaceController : SurfaceController

    {
        [HttpPost]
        public ActionResult Contact(ContactModel model)
        {
            if (ModelState.IsValid)
            {
                var sb = new StringBuilder();
                sb.AppendFormat("<p>Meddelande: {0}</p>", model.Message);
                sb.AppendFormat("<p>Namn: {0}</p>", model.Name);
                sb.AppendFormat("<p>E-post: {0}</p>", model.Email);
                sb.AppendFormat("<p>Telefon: {0}</p>", model.Phone);

                library.SendMail("noreply@test.se", "info@test.se", model.Subject, sb.ToString(), true);

                return RedirectToUmbracoPage(model.ThankYouPage);
            }
            return CurrentUmbracoPage();
        }


    } }

Model

namespace test.Models
{
    public class ContactModel
    {
        [Required]
        [DisplayName("Ärende")]
        public string Subject { get; set; }
        [Required]
        [DisplayName("Namn")]
        public string Name { get; set; }
        [Required]
        [DisplayName("E-post")]
        public string Email { get; set; }
        [DisplayName("Telefon")]
        public string Phone { get; set; }
        [Required]
        [DisplayName("Ärende")]
        public string Message { get; set; }
        public int ThankYouPage { get; set; }
    }
}

Partial View

@model test.Models.ContactModel

@using (Html.BeginUmbracoForm("Contact", "ContactSurface", null, new {@class = "contact-form" }))
{ 
    @Html.ValidationSummary(true)

    <div>

        @Html.LabelFor(x => x.Subject)
        @Html.TextBoxFor(x => x.Subject)
        @Html.ValidationMessageFor(x => x.Subject)

        @Html.LabelFor(x => x.Message)
        @Html.TextAreaFor(x => x.Message)
        @Html.ValidationMessageFor(x => x.Message)

        @Html.LabelFor(x => x.Name)
        @Html.TextBoxFor(x => x.Name)
        @Html.ValidationMessageFor(x => x.Name)

        @Html.LabelFor(x => x.Phone)
        @Html.TextBoxFor(x => x.Phone)
        @Html.ValidationMessageFor(x => x.Phone)

        @Html.LabelFor(x => x.Email)
        @Html.TextBoxFor(x => x.Email)
        @Html.ValidationMessageFor(x => x.Email)

        @Html.HiddenFor(x => x.ThankYouPage)

    </div>
    <input type="submit" value="Skicka" class="btn-accept" />
}

And it´s here I get the error message on the first line

@using test.Models
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{
    Layout = "uBlogsyBaseSite.cshtml";
}

@Html.Partial("ContactForm", new ContactModel { ThankYouPage = Model.Content.GetPropertyValue<int>("thankYouPage") })

What have I missed?

EDIT: Sry, I´m using Umbraco 7.0.3 and .net 4.5.

Thanks, Jonas
