I feel I need to clarify this - my post is aimed specifically at optimizing code for high performance. Many of those tips will reduce readability of the code, which may make it harder to determine its correctness. I'm a big fan of LINQ and I use it in my own code, just not in the high-perf bits. LINQ is great for writing code which has "obviously no deficiencies" in terms of correctness. Without it your code may end up having "no obvious deficiencies". I also like LinqFaster, LinqAF and these other libraries/tools which can make LINQ usable in more domains.
