As has been explained in this MSDN article , FrontPage Server Extensions from Microsoft is required for publishing applications to a Windows Web server that uses HTTP.
By default, Windows Server does not have FrontPage Server Extensions installed. If you want to use Visual Studio to publish to a Windows Server Web server that uses HTTP with FrontPage Server Extensions, you must install FrontPage Server Extensions first. You can perform the installation by using the Manage Your Server administration tool in Windows Server.
1. Create a FTP user in your web hosting server. Make a note of the FTP address and the username - password of the user.
2. In the Visual Studio, open your project and go to Properties >> Publish.
Enter the FTP address URL in the Publishing Folder Location as shown below. (In our example it is ftp://ftp.mywindowshosting.com/).
Enter the URL which your application should be installed or viewed from. (In our example it is http://aparnachinya-001-site1.mywindowshosting.com/)
3. Now, click on Options >> Deployment (mention the name of the file through which you want to initiate the ClickOnce deployment, which In our case is default.htm)
4. Click on Publish. It will ask for the FTP Log On Credentials here.
5. Go to the website URL and you will find your application ready to be installed!
