Hi, I've created a database in my windows phone 8 application:

private void Application_Launching(object sender, LaunchingEventArgs e)
 {
     using (CantiContext db = new CantiContext("isostore:/canti.sdf"))
     {
         if (db.DatabaseExists() == false)
         {
             // Create the database.
             db.CantoTable.InsertOnSubmit(new Canto() { Name = "CantoTest" });
             db.SubmitChanges();
         }
     }
 }

Now i want to now how to drop this database for recreate it.

Thanks!
