Answer 1

Please explain your question a bit more
1) Connection string is a very good way to make a connection to a database. But it will not search you data.
2) Entity framework
3) Linq is more a query method than a way to connect to a database. With linq you need to have data available to be able to search it.
I guess you need all three.
What do you want to do ?
