It’s a data-driven world...we all need to know how to live in it.

Gone are the days when you could program for days, even weeks, without dealing with loads of data. Today, everything is about data, and that’s where LINQ comes in.

You’ll use anonymous objects to manage your data in new and interesting ways. You’ll add unit tests to make sure your code is working the way you want. Once you’ve got the hang of wrangling your data into manageable chunks, you can use lambda expressions to refactor your C# code to make it easier to work with and more expressive.
