Getting a SQL connection using Entity Framework

I learned that the magic number is ExecuteStoreCommand().

  new AdventureEntities().ExecuteStoreCommand(
        @"    UPDATE Users
              SET lname = @lname 
              WHERE Id = @id",
        new SqlParameter("lname", lname), new SqlParameter("id", id));

When this happens, an explicit Connection is not required, which really makes the code much clearer. All of the following code was replaced with the one-liner above.

  using (SqlConnection con = new SqlConnection("Persist Security Info=False;Integrated Security=true;Initial Catalog=Remember;server=(local)"))
  {
    con.Open();
    using (SqlCommand cmd = con.CreateCommand())
    {
      cmd.CommandText = @"
          UPDATE Users
          SET lname = @lname 
          WHERE Id = @id";
      cmd.Parameters.AddWithValue("lname", lname);
      cmd.Parameters.AddWithValue("id", id);
      cmd.ExecuteNonQuery();
    }
  }
