LINQ isn't a magic bullet.

   collection.Where(s=>s.Transaction.Amount < 100).OrderBy(s=>s.Name).Single();

I'll let you debug the intermittent NullReferenceException that threw in production with no PDBs...

[Bognar]

You would get a null reference exception if you unrolled that into a loop, too. You should know what your data is going to look like and if any elements could be null or not. Don't blame LINQ for your lack of null checking.

[bananas]

Yep but you'd know which dereference it was if you unrolled it. Nulls happen unfortunately even with the best checking and intents.

But look at how concise and readable that is!
