1. Subscribe to Azure guaranteed zero cost account, see Step-by-step guide

1. Create new project (you can use a new empty solution) (Visual C# → Web → ASP.NET MVC3 Application).
2. Use project template - Internet application with an account controller that uses forms authentication.
3. Test application locally
4. Study application (role) structure. Identify parts of MVC.
5. Open Site.Master view, add item called “Submit message” into menu.
   1. If you have time, rewrite the default content in order to represent a simple message board.
6. Extend corresponding controller (Home) and add a new view (Insertion).
7. Add new model MessageModel
8. Add action Insertion for storing message board messages.
9. Implement simple static class SimpleStorage to provide data container for messages.
10. Provide Index view with messages model (from corresponding controller).
11. Output content of MessagesModel in Index view.

    public class MessageModel
    {
        [Required]
        [DataType(DataType.Text)]
        [Display(Name = "Your Message")]
        public string Message { get; set; }
    }

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication1.Models.MessageModel>" %>

<asp:Content ID="aboutTitle" ContentPlaceHolderID="TitleContent" runat="server">
    Message submission
</asp:Content>

<asp:Content ID="aboutContent" ContentPlaceHolderID="MainContent" runat="server">
    <h2>Message submission</h2>

       <% using (Html.BeginForm()) { %>
       <div>
            <fieldset>
                 <div class="editor-label">
                    <%: Html.LabelFor(m => m.Message) %>
                </div>
                <div class="editor-field">
                    <%: Html.TextBoxFor(m => m.Message)%>
                    <%: Html.ValidationMessageFor(m => m.Message)%>
                </div>
            </fieldset>
                <p>
                    <input type="submit" value="Uloz vzkaz" />
                </p>
        </div>      
    <% } %>      
</asp:Content>

        [HttpPost]
        public ActionResult Insertion (MessageModel model, string returnUrl)
        {
            SimpleStorage.Messages.Add(model.Message);
            return RedirectToAction("Index");
        }

    public class MessagesModel
    {
        [DataType(DataType.Text)]
        public List<string> Messages { get; set; }
    }

1. Add new project (Cloud → Windows Azure Project)
2. Don't add any roles (we will use the current one)
3. Add MVCApplication1 to Azure project roles (Roles→Add→Web Role Project in solution)
4. Configure the only web role (WindowsAzureProjectx → Roles → MvcApplicationx → right click).
   1. Instance count = 2
   2. VM size = extra small
5. Test application locally (if possible)
6. Cloud deployment
   1. WindowsAzureProjectx → right click → publish
   2. Choose your subscription → manage → new
   3. Create new certificate, enter a friendly name
   4. Copy full path of the certificate to clipboard
   5. Go to windows azure portal → management certificate
   6. Right click on your subscription → Add certificate → browse
   7. Copy path to address bar → select certificate → click ok
   8. Copy Subscription Id from Windows Azure Management Portal
   9. Go back to Visual Studio and paste the Subscription Id
   10. Choose your new subscription → Next
   11. Leave settings as it is → Next → Publish
7. Wait until the role is published and the environment started. Test the deployment online. What is the problem?
