Help with sql server setup application to install the progr

Question

Hi there
As you know from within Visual Studio to easily build a setup program that was created
And will be required to put together a program during installation, it can also be installed on the user's system.
---------
Unless you want to install SQLServer express is located right next to me for the full version and install the main configuration (I mean that in the same way to install the full version)
When you install some software, SQLServer is installed automatically when you install it anymore and he needs someone config automatically installed.
If the setup in the Visual Studio default settings that the program does not require near Harrow and download from the site itself, surprising herself to download and automatically install itself
I would like to know in what way that does not require the user to download and install the hardware installed SQLServer is confused, very easy to install itself and does all the work
Thank
