When deploying a website  or a web service using Visual Studio 2010 we can use  a new deployment functionality called Build Deployment Package; this builds a zip file that you can import in IIS. The default location of zip is at ProjectFolder\obj\Debug\Package\.

 

However in IIS Manager, the default installation doesn’t include option to import our package, additional components need to be installed called Web Deploy (download). After installing the add-on you should be able to see the import option in IIS.
