WebDeploy: LocalDB, SQLServer Express, ISS 7.x

After some research I came to conclusion that LocalDB that is per default provided with VisualStudo 2013 "built-in" storage does not work in conjunction with WebDeploy resp. IIS 7.x at all.

The VisualStudio 2013 auto-generated <magiccrypticnaming>.mdf database file is deployed successfully to IIS App_Data Folder without any database settings in the publishing dialog but it seems that is not loadable by the IIS infrastructure solely. I am a naif.

There it is, in black and white:

"LocalDB is not designed to work in IIS, so for your test environment you need to have SQL Server Express installed. If you are using Visual Studio 2010 SQL Server Express is already installed by default. If you are using Visual Studio 2012, you have to install it."

Otherwise using the database settings within publishing dialog and the deployment fails spitting out:
