Starting with the .NET Framework 4.5 and Visual Studio 2012, deployment is handled by Visual Studio using the Publish option , which creates the deployment folder. This is not the same kind of deployment folder produced by earlier Web Deployment projects. Once the Visual Studio deployment folder is produced, simply copy it to a folder on your production server and import the deployment package to IIS.

See the documentation from Microsoft for Web Deployment Overview for Visual Studio and ASP.NET

Step 1: Copy the deployment package from the development machine to the server.

Copy or FTP the deployment package to a location on the server.

Step 2: Open IIS Manager on the server and open the ‘Import Application’.menu.

In IIS Manager select the deployment package from the location where it has been copied.

See the deocumentation from Microsoft for Import a Package through IIS Manager and Manually Installing Web Packages.

Step 3: Select the deployment package.

In the Import Application Package Wizard, on the Select the Package page, browse to the location of your web deployment package, and then click Open or Next.

Step 4: Select the content of the deployment package to be imported.

Step 5: Enter information required to install the package.

Step 6: IIS Manager shows the status of the installation.
