Storing Passwords with ClickOnce

Hello! I was messing around with clickonce applications and was needing some help.

I would like to have a clickonce app run from a users machine. I have no problems connecting to the SQL Server database from the local app. Right now, the username and password for the database is stored in the connection string. What are the best practices for storing database login information in this type of application? Is there a way to secure this information besides just including it in the connetion string?

Thanks!
