Creating your first mvc application - Part 3

Suggested Videos 
Part 1 - Installing mvc
Part 2 - Which mvc version is my mvc application using

In this video we will discuss about
1. Creating an mvc application
2. Understand how mvc request is processed as apposed to webform request

Creating an mvc application:
1. Open visual studio
2. Click File > New Project
3. Select "Web" from "Installed Templates" section
4. Select ASP.NET MVC 4 Web Application
5. Set Name="MVCDemo"
6. Click OK
7. Select "Empty" template. Select "Razor" as the ViewEngine. There are 2 built in view engines - Razor and ASPX. Razor is preferred by most mvc developers. We will discuss about Razor view engine in detail in a later video session.
8. At this point you should have an mvc application created.

Notice that in the solution explorer, you have several folders - Models, Views, Controllers etc. As the names suggest these folders are going to contain Models, Views, and Controllers. We will discuss about Models, Views, and Controllers in a later video session.

Now let's add a controller to our project
1. Right Click on "Controllers" folder
2. Select Add > Controller
3. Set Controller Name = HomeController
4. Leave rest of the defaults and click "Add"

We should have HomeController.cs added to "Controllers" folder. 

At this point run the application by pressing CTRL+F5. Notice that you get an error as shown below.

To fix this error, we need to add a view with name, "Index". We will discuss about views in detail in a later video session. Let's fix it another way. The following is the function that is automatically added to HomeController class
public ActionResult Index()
    return View();

Change the return type of Index() function from "ActionResult" to "string", and return string "Hello from MVC Application" instead of View().
public string Index()
    return "Hello from MVC Application";

Run the application and notice that, the string is rendered on the screen. When you run the application, by default it is using built-in development server. Let's use IIS, to run the application instead of the built-in development server.
1. In the solution explorer, right click on the project and select "Properties"
2. Click on "Web" tab
3. Select "Use Local IIS Web Server" radio button
4. Notice that the Project Url is set to http://localhost/MVCDemo by default
5. Finally click on "Create Virtual Directory" button

Run the application, and notice that the URL is "http://localhost/MVCDemo/"

Now change the URL to "http://localhost/MVCDemo/Home/index"

In the URL "Home" is the name of the controller and "Index" is the method within HomeController class. 

So the improtant point to understand is that the URL is mapped to a controller action method. Where as in web forms application, the URL is mapped to a physical file. For example, in a web application, if we have to display the same message.
1. We add a webform and in the Page_load() event include Response.Write("Hello from ASP.NET Web Forms Application");
2. We then access WebForm1.aspx as shown below
3. The Page load event gets executed and the message string is displayed.

  2. Hi Venkat sir im executing MVCDEMO Application get below error
    Error: JavaScript runtime error: Unable to get property 'appendChild' of undefined or null reference

  3. HI sir

    In properties -web i could not find "Use Local IIS Web Server" radio button. kindly do the needful.

    1. If you are using Visual Studio 2013 there will not be the option for "Use Local IIS Web Server" radio button.

      Instead, look under "Servers" section
      Then, you should see a checkbox for "Apply server seetings to all users (store in project file) This should be checked by default. If it is then make sure the drop down list has "IIS Express" selected. This was my default.

      Next, for "Project Url" make sure that matches what was said in the tutorial. ("http://localhost/MVCDemo/Home/index") IMPORTANT: if there is a port number listed in the Project Url such as mine ("http://localhost:62805") make sure you keep that when you change it. Mine ended up being "http://localhost:62805/MVCDemo" You will need to then click the "Create Virtual Directory Button and you will likely be prompted to create the virtual directory.

      As a side note, if you are curious, like me, and want to know where it puts these settings at you will want to navigate to C:\Users\[USERNAME]\Documents\IISExpress\config and the settings are placed in the applicationhost.config file.
