Professional F# 2.0, Ted Neward, 2011
F# is a high level language that makes good use of multicore processors, not requiring the programmer to put effort into synchronization. I would like to see benchmarks, because there must be considerable overhead. F# is a functional language, and its ancestor is OCaml. This book assumes a good knowledge of .net and has many code examples. Note: you can also use F# on Mono with Linux. 400 pages.
