Create an ASP.NET website from scratch

This walkthrough shows you how to install WebMatrix and use it to build a simple site from scratch. Along the way, you'll become familiar with many features of WebMatrix.
What you'll do
  • Become familiar with the WebMatrix user interface.
  • Use a site template to create a blank site, then add files and code to customize it.
  • Get started with ASP.NET Razor syntax.
  • Install the ASP.NET Web Helpers Library 1.1 and create a dynamic web page that displays a live Twitter feed.
  • Analyze requests to your website and find errors.
  • Add a database with a table and data to your website, then use a WebGrid helper to display the data in a web page.
  • Run an analysis of your website to enhance its visibility to search engines.
  • Learn how to find web hosting and publish your site to the web.
What you'll need
To run the steps in this walkthrough, you must be running Windows XP SP3 or a later version of Windows.

Introducing WebMatrix

Seamless, simple, small, and best of all, free, WebMatrix includes a complete collection of web development tools that installs in minutes. It elegantly integrates a web server with database and programming frameworks to create a single, integrated experience.  Use WebMatrix to streamline the way you code, test, and publish your own ASP.NET or PHP website. Or start a new site using the world's most popular open source apps, like DotNetNuke, Umbraco, WordPress, or Joomla. With WebMatrix on your desktop, you're using the same powerful web server, database engine, and frameworks that will run your website on the internet, which makes the transition from development to production smooth and seamless.

Getting WebMatrix

To install WebMatrix, you can use Microsoft's Web Platform Installer (Web PI 3.0), which is a free application that makes it easy to install and configure web-related technologies. You can install the Web Platform Installer from the WebMatrix download page.
On the download page, click Install Now. At the security warnings, click Run. On the Web Platform Installer page, click Install.

On the Web Platform Installation screen, WebMatrix displays a list of additional required components. Click I Accept. The install begins.

Creating Your First Website

Right out of the box, WebMatrix gives you a number of options for how to create sites. You can create a site from a template or from a folder that already contains ASP.NET web pages. Or you can download an open-source application from the gallery as the basis for your site.
image02
For this walkthrough, click Site From Template to see a list of available templates.
image03
Select the Empty Site template to create a new site from scratch, and name it WebMatrixDemo. Click OK.
image04
Before moving on, let's take a quick look around the WebMatrix user interface. In the lower-left part of the page you see that you can select one of four workspaces. When you open WebMatrix and select a site, you start off in the Site workspace, which lets you perform tasks like specifying site settings (for example, designating a default web page) and monitoring HTTP requests.
To create, delete, and update files such as web pages, select the Files workspace. The site's folder structure appears in the left pane, and when you select a file, you can edit it in the content pane on the right.
image05
To add a database to your site and then add tables and data to it, select the Databases workspace. You get a list of databases in the left pane, and the content pane changes depending on what you want to do with a selected database.
image06
Finally, to get information about how to help your site rank high in search engine results, select the Reports workspace. Once you've run some reports, you'll see them listed on the left, and when you select one, you'll see the reports contents on the right.
image07
You might have noticed that across the top of the page is a Quick Access Toolbar and a ribbon, like in Microsoft Office 2010. Some of the buttons on the ribbon's Home tab are different in each workspace, but the buttons in the Site group are always the same.
image08
You use My Sites to choose a site to work on, Publish to make the site publicly available, Run to test the site in a browser, and Start/Stop/Restart to work with the web server that you'll use in WebMatrix to test your website (IIS Express).  You'll learn more about IIS Express in a minute.

Adding an ASP.NET Web Page to Your Site

To get a feel for how to work in WebMatrix and what you can do with it, begin by creating a web page. Select the Files workspace and then click New. You get a list of templates to choose from for various file types.
image09
Select the CSHTML template and call the new page Default.cshtml. The extension .cshtml indicates that this is an ASP.NET Web page. It can contain HTML, JavaScript, and CSS, just like a normal HTML page, and you can make the page dynamic by adding special code that runs on the server.
Click OK.
The CSHTML template creates a new page with some basic HTML.
image10
As you can see, this is ordinary HTML markup.  Add some simple "Hello World" HTML to it.
image11
Now click the Default.cshtml file in the navigation pane and then click the Run button to see this page in the browser.
image12

Creating Dynamic Web Pages

You can use helpers in ASP.NET Web pages to create dynamic web pages with a minimum of code. A helper packages commonly used functionality in a way that's easy to write code for. (In other words, helpers package functionality that it would be a lot more trouble to implement if you had to code it all yourself.)  To use helpers, you have to install the Microsoft ASP.NET Helpers Library.
Click Run to run the Default.cshtml file again. In the address box of your browser, remove the Default.cshtml file name from the URL and replace it with _Admin. The resulting URL will look similar to the following (it's ok if your URL displays a port number other than 8080):
http://localhost:8080/_Admin
Press Enter to browse to a page that lets you administer your site. Because this is the first time you're logging into the _Admin page, it prompts you to create a password and guides you through some steps to ensure your site's security. After you do that, click Install packages from an online feed.
image12a
Next, click the Install button next to the ASP.NET Web Helpers Library 1.1 package.
image12b On the next page, click Install to start the installation.
image12c When the installation completes, the _Admin page displays the result.
image12d
Now that you have the helpers installed, we'll show you how simple it is to create dynamic (programmed) web pages. Go back to WebMatrix. In the Files workspace, click New. Create a new CSHTML page named Twitter.cshtml and add some HTML and code to it:
image13
In this example, just a single line of code displays a box of dynamically scrolling tweets from a Twitter user. The Twitter user in this case is "Microsoft". Twitter.Profile is an example of how to use a helper. This is just one of many helpers that ASP.NET makes available. Other helpers do things like upload and crop images, play video clips, and display data from a database.
Select the Twitter.cshtml file in the navigation pane and then click Run, and there they are -- the tweets you asked for are in your browser. (The style of the box is fully customizable, of course; this is the default appearance.)
image14
That's all there is to it—you've created a page that displays a Twitter feed, using simple HTML and one ASP.NET helper.
For more information about using WebMatrix Helpers and programming with Razor Syntax, see the WebMatrix Book.

Testing Your Site

WebMatrix includes IIS Express, which works much like IIS, the commercial Web server from Microsoft. However, IIS Express is integrated with WebMatrix and runs on your local computer, which makes it easy to test your site without having to copy your files to a public server and test them there.
Sometimes you need to do more than just see how pages look in a browser in order to test a site. You might want to know what's going on behind the scenes when a request comes in to your site. For example, are there broken links in your pages? The Requests tool lets you know where there might be problems in your site, and it can take you directly to the file to make a fix.
Select the Site workspace and then click Requests in the ribbon to see the Requests tool, and then click Only Errors to see only the errors.
image15
The first two examples show that a 404.0 error code was issued because your site does not have a favorites icon. To see details about the error, you can click the line with the 404. WebMatrix then shows you details about the error, the name of the page that contains the broken link, and links to resources for more information.
image16
For more information about using WebMatrix to analyze requests to your website, see Analyze Requests to your Website.

Working with Data

Many websites need to keep information in a database. WebMatrix includes Microsoft SQL Server Compact 4.0, which you can use to create databases for your website without the need for full SQL Server. With SQL Server Compact, it's easy to publish your website, because everything is in files in your website folder. (If your website traffic grows and you need more database capabilities, WebMatrix also can automate the process of migrating your data to full SQL Server.)
Whether you use SQL Server Compact or full SQL Server, you can use WebMatrix to create a database, create tables and columns, and add and display data. To see how to work with a database, switch to the Databases workspace. Add a database by clicking New Database.
image17
Next, create a table and define some columns for it. In the navigation pane, click Tables, and then click New Table in the ribbon to create the table.  Click New Column to add columns in the table designer. Add the following columns:
image18
Click the Save icon in the Quick Access Toolbar and name the table Product.
image18-5
Next, select the new table in the navigation pane. In the ribbon, click Data to use the built-in table data editor to add some data:
image19
Ok, you've got some data … now how do you display it? Easily, using another ASP.NET helper, namely the WebGrid helper. In the Files workspace, create another CSHTML page named ListProducts.cshtml and add the following code:
@{
    var db=Database.Open("WebMatrixDemo");
    var grid=new WebGrid(db.Query("SELECT * FROM Product ORDER BY Name"));
}
DOCTYPE html>
<html>
    <head>
        <title>Productstitle>
        <style type="text/css">
            table {border-collapse:  collapse;}
            td, th {border:  solid 1px; }
        style>
    head>
    <body>
        <h1>Productsh1>
        @grid.GetHtml()
    body>
html>
Select the ListProducts.cshtml file in the navigation pane and then click Run. The browser displays a simple table with sortable columns:

Optimizing Your Site

WebMatrix has a built in search-engine optimization (SEO) tool that inspects your website and provides suggestions that can help increase the ranking for your web pages. The tool shows you the optimizations that you can make, and points you directly to the pages that you need to edit. To create a report, select the Reports workspace and click Create a report for the site in the content pane.  The report lists the errors that were found.
image21
This report says there's a problem with the one of the pages. Double-click the localhost URL to expand it and see what the problem is.
image22
For each error, WebMatrix explains what the problem is, makes recommendations for fixing it, and provides links to more information. At this point, you can click Edit this page, which will take you directly to the page in the editor where you can fix the problem, or you can click View More Details to get more information about the error. In this case, if you click Edit this page, WebMatrix will open the Default.cshtml file so that you can add the missing description.
For more information about using the Reports feature in WebMatrix, see Use WebMatrix to optimize your site for search engines.

Getting on the Web

When you're ready to show your application to the world, WebMatrix helps you by introducing you to web hosting partners so that you can find the one that meets your needs.  On the ribbon, click Publish, and then select Find Web Hosting to see hosting offers in your browser.
image23
To publish your site, WebMatrix has built-in support for FTP and Microsoft Web Deploy, which is a one-click publishing solution. Once you've established an account with a hosting provider, import or enter your account settings into the WebMatrix tool. Then all you have to do to publish your site directly from WebMatrix is click Publish. It's as easy as that!
