The first step in planning to build an ASP.NET website on IIS 8 is to install IIS along with the ASP.NET modules and to add your application files to IIS.

The following list shows the tasks required to complete this step:

When you are done with these tasks, record your design decisions before going on to Step 2: Plan ASP.NET Settings.

An ASP.NET Web server is an extended IIS server that has the ASP.NET runtime extensibility model integrated into the core server. The ASP.NET server configuration adds the following IIS modules to the default IIS web server installation:

  • ASP.NET 4.5

  • .NET Extensibility 4.5

  • ISAPI Extensions

  • ISAPI Filters

To install IIS 8 on either Windows Server® 2012 or Windows® 8, you must sign on as a member of the Administrators group.

By default, Windows Server 2012 and Windows 8 installs .NET 4.5 only. If you want to run .NET 2 applications, install .NET 3.5, which supports web applications written using ASP.NET 2 to 3.5.

An application is a grouping of content at the root level of a website or a grouping of content in a separate folder under the website root directory. When you add an application in IIS 8, you designate a directory as the application root, or starting point, for the application. Then specify properties specific to that particular application, such as the application pool that the application runs in.

To configure your ASP.NET application on an IIS website, provide the following information:

  • Alias: The alias is used as part of the application root URL and should be short and descriptive. For example, the alias marketing added to Default Web Site on the local host computer, would produce the following URL: //localhost/marketing.

  • Application pool: An application pool enables an application or a group of applications to run in isolation from one or more applications in another application pool.

  • Physical path: The local path to the application files on the server.
