Take the 2-minute tour ×  I own the first edition of Expert F#
by Don, et al. and I'm considering buying the next edition,
Expert F# 2.0. But I'm wondering if it's worth it. Sure the
syntax will be updated and all, but I'd be more interested if
there were new topics covered or just compelling expanded
coverage of the same topics otherwise.  Glad to hear from anyone
who owns both editions, thanks.  share|improve this question add
comment  1 Answer  up vote 2 down vote accepted  The difference
is not big, Expert F# 2.0 is a minor revision of Expert F#. If
you already know F# and occasionally reference the Expert F#
book, then you don't need to buy a new one.  The change from the
time Expert F# was written to the present is mainly the library
part, and a little bit syntax (e.g. the -> operator in the seq
computation expression).  But for a beginner who wants to try
the examples in the book, the new version is better as the code
examples in the old one may have little incompatibility with the
F# 2.0 compiler.  sh
