Peter starts off with a perfectly good solution to a problem but then complicates the problem . . . and ends up moving to a different design pattern. While on that journey he has some best practices around designing Data Transfer Objects.
You probably use ToList to convert your LINQ results into Lists. It's almost as easy to convert any collection into a Dictionary whose items you can retrieve by key.
As a company's problems continue to become more complicated, your code will become more complicated. Peter shows how refactoring code can lead you to better designs.
Peter gets an improved tip from one reader and some more tips from another, all designed to navigate Visual Studio faster.
Sometimes life is like playing Whack-a-Mole: You write some code that solves a problem, and then someone comes along and makes the problem harder. Here's how to continuously integrate new solutions without having to rewrite your old solutions (much).
Peter didn't bother doing any performance testing but he believes that this change has just got to speed up your ASP.NET MVC application.
You can turn on logging for your Entity Framework code with a single line. Configuring it to write to a file takes only a little bit more effort.
