title: Connection String to Connect to .MDF
body: <p>I've created a new project in VS2008, and added a .MDF file to the project.  This is the first time I've tried to use the MDF files and .SQLEXPRESS databases (I've always used extenal Oracle servers in the past).</p>
  
  <p>I'm trying to document everything as I go, but I can't figure out what credentials are being used to connect to the .MDF file.  Is there an easy way to find out?</p>
