Many computers today ship with multiple processors and with multi-core processors.

In order for programs to take advantage of multiple cores, application developers need to write code that runs in parallel - that is that runs simultaneously on two or more cores. The upcoming .Net 4.0 provides tools to make it easier for developers to write such code.

The Parallel Extensions library eases the pain of building multi-threaded applications. Enhancements include a set of APIs to abstract away the complexity of parallel processing; a set of thread-safe collections appropriate for use with parallel processing; and enhancements to the System.Threading namespace.

Stephen Toub of the Microsoft's Parallel Computing team is touring the Midwest this week speaking about this new technology. Friday October 30, Stephen will be at the Microsoft office in Southfield, MI at a special meeting of the Great Lakes Area .Net User Group.

Microsoft ASP.Net MVC (aka "MVC") is a new framework from Microsoft designed to encourage loose coupling between the user interface and the data layer of a web application. With MVC, an application is logically divided into the Model (the data), the View (the user interface) and the Controller (code to retrieve and manipulate data before passing it to the View). This framework makes it nearly impossible to add business logic (or any code for that matter) to the UI layer; Business logic in an MVC application belongs in either the Model or the Controller. MVC allows for greater separation of concerns, more control over the HTML output and easier unit testing of a greater percentage of your code.

Professional ASP.NET MVC 1.0 by Rob Conery, Scott Hanselman, Phil Haack and Scott Guthrie describes the framework, how to use it, and how to exploit these advantages.

A significant part (about 40% of the text) of this book can be downloaded free. Chapter 1 - the free download written by Microsoft VP and cyber-celebrity Scott Guthrie - describes an ASP.NET MVC application called 'Nerd Dinner'.  This is the chapter I spent the most time on. I used Nerd Dinner as a model to build my own MVC application, striving to understand why the code was written as it was and how the framework was used. For me, this was the most useful part of the book.

This is not to say that the rest of the book is useless - It was very informative. I especially liked the chapters that dove deeper into explaining the Routing Engine, the Controllers and the Views. These chapters weren't comprehensive enough to be a definitive reference, but they were clear and concisse and I learned the flexibility of this framework and alternative ways to use it.

Other chapters describe how to use JQuery and Ajax to make MVC applications more dynamic and visually appealing. The authors devoted two chapters to testing because this is one of the major benefits of MVC.

The final chapter describes how to integrate MVC and the traditional web forms framework into a single application. I appreciated this because so much of my work is modifying existing systems.

My recommendation is to download and read the free chapter of this book before deciding whether to invest the 50 bucks on the larger dead tree version. This will give you a better perspective on the framework and you will make the rest of the book more relevant. If your goal is simply to evaluate this framework or get exposure to it, this chapter may be sufficient.

But if your interest is piqued by Nerd Dinner, the remainder of this book is a good start in learning MVC.

Think big; act small; fail fast; learn rapidly.

These are some of the lessons from Tom and Mary Poppendieck’s book Lean Software Development – An Agile Toolkit.

The Poppendiecks take what they learned from Lean Manufacturing (many of which were originated with the pioneering work of Toyota Motor Company) and apply these lessons to software development.

They deliver advice in the form of 22 “tools” that can make a team or project more lean. Related tools are grouped together into chapters.

The authors recommend that organizations define, find and eliminate waste wherever it occurs in a process. Examples of waste in software development include defects, waiting, extra features or processes, and any non-essential activity. To assist finding waste, they recommend Value Stream Mapping - a technique in which one lists in sequences all the steps from customer request to delivery and estimates the time to completion of each step and the wait time between each step. This technique often makes bottlenecks obvious so that they can be reduced or eliminated.

Many of the tools in this book overlap. For example, iterations and feedback are listed as separate tools, but shorter iterations allow for more frequent feedback to the development team. Short iterations also expose design problems more quickly sot that the can be corrected early in the development cycle at a lower cost.

Much of the authors’ advice seems counter-intuitive. For example, they recommend against detailed planning at the start of a project and attempting to optimize every part of a multi-part project.

A popular approach among software project managers is to create in advance a detailed plan of every step in the design, development and deployment process and to estimate each step. To do so, you need to know a specific scope of everything you will build. This makes sense as a risk-reduction strategy, until you consider that environments, requirements, priorities and people often change while software is being developed. A rigid plan created up front often requires an aggressive change control process to alter that plan in any way. And for long-term projects, the changing landscape almost always forces changes to the design. Also, when users know they will only get one chance to request features, they tend to ask for far more, so scope tends to get bloated when projects are planned in this way. A better approach is to re-evaluate priorities periodically throughout the development process and keep focused on the top priority features that have not yet been implemented.

Complex project can and often should be split into a number of smaller phases or tasks. This helps to simplify the complexity. Many managers then strive to optimize each phase of the project, assuming that this goal will lead to overall optimization of the project. The Poppendiecks advise against this goal because optimizing some phases may cause a bottleneck in your overall project, thus slowing down the project as a whole. A buildup of code waiting to be tested, for example, represents waste that should be eliminated. It is best to look at the system as a whole when setting optimization goals. Optimizing each part ignores the interaction between these parts.

The book finishes with practical advice to get started making your team and process more lean.

Lean Software Development - An Agile Toolkit is a clearly-written, thoughtful book and anyone involved in software development projects can benefit from reading it.

HopeMongers is attempting to connect people together via charitable donations. The web site HopeMongers.org allows individual contributors to donate small amounts of money (they use the term "Microgiving" to describe this) to individual projects that help the poor of the world.

By doing so, they eliminate much of the bureaucracy and cost that burdens many other charitable institutions. The projects that HopeMongers supports tend to be small in size and focused on an individual community. Examples include digging a well to provide clean drinking water for a village in Haiti; construction of a building to house an orphanage in Uganda; and a computer education center in South Africa.

"All the money that's donated to HopeMongers goes to the project" said lead architect Phil Japikse.

On the web site, each project lists the amount needed to fully fund it and the amount raised so far.

Sam Henry of Microsoft is the driving force behind this site and he has traveled around the world seeking, vetting and overseeing projects to show on the site.

But many others are involved in the development of the web site.

DiscountAsp.net donated the web hosting; SAAS hosts TFS and the build servers for free; and most of the development time was donated by dozens of talented developers. Those who didn't volunteer worked on the project at a discounted bill rate.

The development team was spread across the US and worked part-time, which presented a number of challenges. For instance, most of the collaboration took place between 10PM and 1AM Eastern time, via LiveMeeting. For those interested in the technology, the site is built using ASP.Net web forms built with JQuery, C# and NHibernate.

The site is now live and accepting donations. Visit http://www.HopeMongers.org  to learn about the projects and to give a little. You can even donate to the HopeMongers project itself from the site.

I gave $10 to help provide clean drinking water to a village in Uganda and I feel better for having done so.

The ASP.NET MVC framework (which I will refer to as "MVC" in this article) encourages greater separation of concerns than the older ASP.NET web forms framework.

Some key differences between web forms and  MVC are

  • ASPX pages in MVC have no code-behind files. This discourages developers from putting any business logic in the view.
  • By default, URLs in MVC do not point to a file on disc. Rather, they point to an Action in a Controller.

A controller is a class that inherits from System.Web.Mvc.ControllerBase.

MVC uses several conventions to find this class. First, it expects controller classes to be in the Controllers folder. Also, it expects a controller class name to end with "Controller".  So if we tell MVC to look for a Product controller, it will look for the file Controllers\ProductController.cs or Controllers\ProductController.vb.

An Action is a method within a Controller class that returns a System.Web.Mvc.ActionResult. The ActionResult represents the View data that is available when MVC renders output to the client.

One way we can tell MVC to look for a controller is by typing a URL into the browser’s address bar. Doing this causes MVC to use the routing engine. I described the routing engine in a previous article. The default routing assigned to a new MVC project looks for a URL with the following format


When the routing engine encounters a URL formatted like the one above, it looks for a controller named after the first part of the URL; an action method within that controller named after the second part of the URL; and a parameter to pass to that method in the third part of the URL. For example, if the user typed the following URL into the address bar:


, MVC would look for a class named CustomerController in Controller\CustomerController.cs (assuming we are coding in C#). If it found this class, it would look in it for a method named "Details" that returns an ActionResult and that accepts a parameter. It would then call the Details method and pass it the parameter "1".

The ActionResult returned by this method is used by the MVC View engine to render output to the client. I described MVC views in a previous article.

The code below is for a Controller Action method. It assumes the existence of the GetCustomer method that returns a single customer object.

public ActionResult Details(Int32 id)
    Customer cust = MVCDemoRepository.GetCustomer(id);
    return View(cust);

The View method called in the code above returns a ViewResult – a class that inherits from ActionResult. By passing the Customer object to this method, the ActionResult’s Model property is populated with the Customer object. Properties of that object can then be used within the view.

Another way to pass data from the controller to the view is to populate the ViewData property. ViewData is a list of name-value pairs. You can populate this list in the controller and retrieve elements from it within the view. We can modify the Action method above to add to the ViewData list.

public ActionResult Details(Int32 id)
    ViewData["HelloMessage"] = "Good morning to you";
    Customer cust = MVCDemoRepository.GetCustomer(id);
    ViewData["GoodbyeMessage"] = "Good night. See you later";
    return View(cust);

By default, this controller routes the user to a view with the same name as the Action in a folder named after the controller. In this case, MVC will look in the \Views\Customer folder for a file named either Details.aspx or Details.ascx. If it cannot find either of these files in that folder, it will search in the Views\Shared folder. Here MVC is using configuration again to determine where to look for files.

You can change the view MVC looks for by using an overload of the View method as in the following example

return View("CustomerDetails", cust); 

The above line tells MVC to look for a view page named CustomerDetails.aspx or CustomerDetails.ascx in either \Views\Customer or \Views\Shared.

Here is a complete listing of a Controller class

using System;
using System.Collections.Generic;
using System.Web.Mvc;
using MVCDemoController.Models;

namespace MVCDemoController.Controllers
    public class CustomerController : Controller
        // GET: /Customer/
        public ActionResult Index()
            List<Customer> customers = MVCDemoRepository.GetAllCustomers();
            return View(customers);

        // GET: /Customer/Details/1
        public ActionResult Details(Int32 id)
            ViewData["HelloMessage"] = "Good morning to you";
            Customer cust = MVCDemoRepository.GetCustomer(id);
            ViewData["GoodbyeMessage"] = "Good night. See you later";
            return View(cust);

Below is a sample view to render the output from the Details controller action above

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

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">


    <%=Html.Encode(ViewData["HelloMessage"]) %>
            <%= Html.Encode(Model.ID) %>
            <%= Html.Encode(Model.FirstName) %>
            <%= Html.Encode(Model.LastName) %>
        <%=Html.ActionLink("Back to List", "Index") %>
    <%=Html.Encode(ViewData["GoodbyeMessage"]) %>



Good morning to you

ID: 1

FirstName: David

LastName: Giard

Back to List

Good night. See you later

The MVC Controller is used to retrieve data from the Model, to populate any extra data needed by the view and to determine which view to render. Understanding it is key to understaning MVC.

The ASP.NET MVC framework (which I will refer to as "MVC" in this article) encourages developers to work closer to actual rendered HTML than does the more traditional web forms ASP.NET framework. The web form framework abstracted away much of the HTML, allowing developers to create sophisticated web pages simply by dragging controls onto a design surface. In fact, with the web forms framework, it is sometimes possible for someone with no knowledge of HTML to build an entire web application.

But MVC’s view engine removes that abstraction, encouraging users to write more of their own HTML. By doing so, developers also get more control over what is rendered to the client.

Some web developers may be surprised to learn that most of the server controls they are used to dragging onto a design surface do not work in MVC. This is because ASP.NET server controls are self-contained objects that encapsulate all their functionality, including the C# or VB code they run. This is contrary to the way that MVC works. In the MVC framework, all business logic code is in either the model (if it applies to the data) or in the controller if it applies to routing or output.

An MVC view consists only of an ASPX page. By default it doesn't even contain a code-behind file.

Let’s analyze a typical MVC view. Like a web form, an MVC view contains a page directive at the top.

<%@ Page Title="Sports" Language="C#" 

The Title, Language and MasterPageFile attributes should be familiar to anyone who has developed in ASP.NET. The meanings of these attributes have not changed in MVC. The Inherits attribute is also used in web forms development, but in this case, we are inheriting from a ViewPage that contains our model.  The model represents the data we wish to render (I will write more about the MVC model in a future article.) By inheriting from a ViewPage, we provide the model data directly to the page and we can strongly type the keyword Model to whatever data type our model is.

Mixed in with the HTML of our page, we can output some server side data by enclosing it in <% %> tags.

If you wrote any web sites with classic ASP (the predecessor to ASP.NET), you probably used these tags. (I recently heard someone refer to them as "bee stingers").  If you place "=" in front of a value or variable, the view engine will output the value or contents of that variable. For example

<%=System.DateTime.Now %>

outputs the current date and time, like the following

10/2/2009 6:08:46 PM

We mentioned earlier that the Model keyword is strongly-typed. For example, If we inherit our ASPX from  System.Web.Mvc.ViewPage<TestMvc.Models.Customer>, then our model represents a Customer object and we can output a property of that model class.

Assuming that our Model is uses the following Customer class:

public class Customer
    public string FirstName { get; set; }
    public string LastName { get; set; }

, we can output the FirstName property with the following markup:

<%= Model.FirstName %> 

You probably already know that it is almost always a bad idea to output text directly for the screen without encoding it, as I did above. Failure to do so may leave your site open to scripting attacks. Fortunately MVC includes an Encode helper method to encode strings for safer output. That helper method (along with other helpers) is available via the Html property of the ViewPage from which our view inherits. We can call the helper method and encode the first name with the following markup.

<%= Html.Encode(Model.FirstName) %>

This outputs the FirstName property, but encodes it to prevent problems if the first name property somehow gets infected with some client-side script.

Other helper methods of the ViewPage give you the ability to begin and end an HTML form, to render an HTML textbox, to render a hidden field, to render an HTML listbox, and perform many other useful functions.

The code below will output a hyperlink with the text "Home" that links to the Index method in the Home controller.

<%= Html.ActionLink("Home", "Index", "Home")%>

Another way to use data in the view is to store it in ViewData. ViewData is a property of the view and contains a dictionary of name/value pairs. You can add a value to this dictionary in the controller with code like the following

ViewData["Greetings"] = "Hello dummy";

and display a ViewData element in the view with markup like the following

<%= Html.Encode(ViewData["Greetings"]) %>

Below is the full markup for a sample MVC view page

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MVCDemoView.Models.Customer>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%= Html.Encode(ViewData["Greetings"]) %>
<%= Html.Encode(Model.FirstName) %>
<%= Html.Encode(Model.LastName) %>    
<%= Html.ActionLink("Home", "Index", "Home")%>

Here is the output of the view page above

Hello dummy
David Giard

If you don’t like the view engine that ships with MVC, it is possible to replace it with your own. Some open source projects, such as Spark have already given users this ability.

Using the MVC view engine encourages developers to have more control over the output sent to the client and provides a greater separation of concerns for the application as a whole.

One of the differences between ASP.NET MVC  and traditional ASP.NET web forms is the URL typed by the user.

In traditional ASP.NET, a URL points to a physical page on disc. Typically one can infer the location of that page by examining the URL. For example, the URL


likely points to a file named MyPage.aspx located in a folder named Folder1.

By contrast, a URL in an ASP.NET MVC application points to an action in a controller. For example, the URL


Tells the MVC framework to pass a parameter of "2" to an action method named Edit in a Customer controller class.

ASP.NET MVC (which I’ll call MVC going forward) uses routing to map a URL to a specific action. Routing is typically configured in the  Application_OnStart method of the global.asax file.  An MVC application contains a System.Web.Routing.RouteTable, which contains a collection of routes on which it can act. When you create a new MVC project, a default route is added to this collection by adding the following code in global.asax.

    "Default",                                              // Route name
    "{controller}/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults

This code adds a route named "Default" to the route table. This route tells MVC to look for a URL structured similar to the following


When it encounters such a URL, it looks for a controller class with a name based on the first part of the URL. By convention, MVC looks for controllers in the "Controllers" folder and is named with the suffix "Controller". So if the first part of the URL is "Customer", MVC will look in the controllers folder for a class derived from System.Web.Mvc.Controller named "CustomerController".

The second part of the URL identifies an action. The action is a method within the controller that returns a  System.Web.Mvc.ActionResult. The ActionResult identifies the view used to render a response (more on that in a later article). So if the second part of the URL is "Edit", MVC will look for a method in the controller class named "Edit" that returns an ActionResult.

The third part of the above URL defines a parameter for the action, in this case a parameter named "id".

The following URL


causes MVC to search for a class named Controllers\CustomerController, to call the Edit method in this class and to pass the value 2 to the id parameter of the Edit method.

What if the URL does not contain all three parts? The Default route above specifies a default value for each of the parts. If the third part of the URL is omitted, no parameter is passed to the Action. For a URL with no id parameter, we will need to create an action method that does not expect a parameter. If the second part of the URL is omitted, the default action is "Index", so MVC will look for a method named "Index" in the controller class. If the first part of the URL is omitted, it defaults to "Home" so MVC will look for a Controller class named "HomeController" in the Controllers folder.

You can use this same syntax to add more routes to your application. Simply add more calls to routes.MapRoute() in Global.asax. MVC will match URLs to these routes in the order listed.

Notice that the RouteTable and RouteCollection are part of the System.Web.Routing namespace and not part of any MVC namespace. This should tell you that the routing engine is not restricted to MVC applications. It can be used in any ASP.NET application if you want cleaner URLs.

If you find a URL like /Customer/Edit/2 more asthetically pleasing than /Customers/EditCustomer.aspx?CustID=2, you should investigate the routing engine.

Microsoft first released ASP.NET almost eight years ago. At that time, they created a model they hoped would be familiar (and compelling) to Windows forms developers, particularly to those working in Visual Basic 6.

ASP.NET adopted a development paradigm that mimicked Windows forms. This programming model was referred to as “web forms” and it abstracted away much of the complexity of HTML and HTTP, easing the transition from Windows to the web for many developers. Using web forms, developers could drag controls, such as buttons and textboxes, onto a design surface and add code that ran automatically when a user interacted with a control – such as when a user clicks a button. Pages and controls had events, such as Load and Init that ran at specified times during a page’s creation. By default, each page had a code-behind file – class containing code that responded to page events. These concepts were familiar to Visual Basic developers and this helped to drive adoption of ASP.NET.

But there are some drawbacks to this model. Web forms abstracted away the details of HTML and HTTP, but this abstraction cost the developer control over the rendering of pages and controls. Some developers felt that the web forms framework got in the way of their web developing by hiding these basic constructs. Also, tying code to web form events made it difficult to test much of the application. Testing frameworks evolved that would mimic the behavior of a web server, just to integrate with automated unit testing frameworks.

Recently Microsoft released ASP.NET MVC - a new programming framework designed to build web applications with HTML and HTTP. This framework uses the Model-View-Controller pattern.

The Model-View-Controller pattern is not new. However the release of ASP.NET MVC (I’ll refer to it as "MVC" going forward) has renewed interest in this pattern.

MVC consists of three main parts. You’ll never guess what they are. Give up? They are the Model, the View and the Controller.

The Model contains the application’s data and any business rules associated with that data. It is up to the Model to retrieve and update data from and to a database (or other persistent data store or back-end), to validate that data and to apply any business rules to that data.

The View is a template for the user interface. It should contain no logic at all. In fact, in the ASP.NET MVC framework, by default View web pages don’t even have a code-behind file. A view in this framework consists only of HTML mixed with some placeholders to output values from the model or helper functions based on those values.

The Controller is the glue that binds the Model to the View. By default, each web request in ASP.NET MVC gets routed to a given method (known as an “Action”) of a given class (known as a "Controller"). This method executes and returns either a view or enough information for the framework to identify and render a view.

MVC has two main advantages over web forms –It is easier to test and it gives more control to the developer.

Separating an application into three distinct parts makes it far easier to test.  Launching a user interface in an automated testing framework, such as NUnit or MSTest is possible but it’s clumsy and slow. Minimizing the code in the user interface allows us to test the code more easily.

MVC also gives the developer more control over the rendered HTML (the view) than is possible in web forms. Web forms deliberately abstract away much of the HTML rendering, while MVC forces the developer to write explicit HTML in his View templates.

The release of ASP.NET MVC certainly does not signal the end of web forms.  Many developers appreciate the abstraction that web forms provides for them. Many web forms still exist in production and I have yet to hear anyone refer to these as "legacy" applications or "Classic ASP.NET".

But for those who want more control over their output, a more pure separation of concerns and easier testability, ASP.NET MVC offers a good option.
