C# LINQ Performance Tips #1 - Let keyword & Custom Lookup

This video will show you some of the performance and allocation problems that you might encounter when writing LINQ expressions we will also see that an expression you see is not necessarily, what you get.

LINQ is not all bad and we will show you an example where LINQ absolutely rocks!

UPDATE: It does not rock :( https://youtu.be/Dv_nsoEmC7s?t=920 The last example was not materialized so what I was measuring is the performance of parsing the query not executing it. Sorry, deal with it :)

This video mentions examples found in my previous video: https://youtu.be/ahnaIdQMoYw
