How to hide XML Configuration File

[RishabhS]

I have just finished making my application and finished building it. And everything is working fine.And then I notice an XML Configuration file in the folder, So I click it.And there it is, my whole connectionstrings along with my remote sql server ip address, login username and login password which is visible for all to see.I tried deleting the XML Configuration file and ran the program, it just makes a App_Data folder inside the folder with a default database.Is there any way to hide the XML Configuration file or make it unreadable, as it contains all my connection info.Thanks.
