programmatically Publish Website using asp.net

This article describes how to create a new web site and publish web site programmatically on IIS using ASP.NET and C#.
On the server side, web service does the job. It takes the website name as parameter and creates new website on IIS. And a point to be noted is all the new websites created point to a same physical location and depending upon the name of the website, content gets populated. If you need to configure different physical paths for each website, send an additional parameter to the web service


Add Reference to “System.DirectoryServices” library and navigate to .cs file and import the namespaces “using System.DirectoryServices”.
