When you run a Web project in Visual Studio, project options determine which Web server Visual Studio uses to run (test) the site.
By default, Visual Studio runs file system Web site projects and Web application projects by using the Visual Studio Development Server.
However, you might want to run a project by using an Internet Information Services (IIS) virtual directory that points to the folder where the project files are located.
For FTP Web site projects, Visual Studio prompts you to specify a server URL the first time that you run the site. You can change the server URL at any time.
You cannot specify that the ASP.NET Development Web server run a local or remote IIS Web site project because Visual Studio always uses the URL where the IIS Web site project was created.

The Visual Studio Development Server option applies only when you are running (testing) the Web project in Visual Studio. Production Web applications always run under IIS. |
