C# Local Database – How to Connect and Use Local Database (Sql Server)

A local database is very essential for developing small
scale C# applications, because it doesn’t requires a server to store the data.
So this article is on how to connect and use C# local database.
Well I am pretty sure that most of you would thing, what is
a Local Database? A local database is database which can be used locally on a
computer, it doesn’t require a server. The advantage of using a local database
is you can easily migrate your project from one computer to another (you don’t
need to setup/configure a database server). Microsoft provides local database
within visual studio which is often called as SQLCE (CE stands for compact
edition).
