title: How to clean up old connections from EDMX Wizard in Visual Studio 2015
body: <p>When using EF Database-First wizard for EDMX creation, there is a dropdown containing connections that were created previously; these may linger around long after the database is no longer relevant. The connections cannot be edited or deleted from the wizard interface, only new ones created.</p>
  
  <p>See screenshot, under "What data connection should your application use to connect to the database?"</p>
  
  <p>Where does dropdown data get stored, because I so want to clean them up / blast them away / nuke them forever / start with a fresh slate?

  <p>I am using Visual Studio 2015, but it's probably the same for other versions.</p>
