Answer 1

Solution 1: See Creating a Virtual Directory for Your Application for detailed instructions on creating a virtual directory for your application.

Solution 2: Your application's Bin folder is missing or the application's DLL file is missing. See Copying Your Application Files to a Production Server for detailed instructions.

Solution 3: You may have deployed to the web root folder, but have not changed some of the settings in the Web.config file. See Deploying to web root for detailed instructions.

In my case Solution 2 works, while deploying to server some DLL's from bin directory has not been uploaded to server successfully. I have re-upload all DLL's again and it works!!
