F#

So anyway I have begun my foray into F#.  Because I plan to use .net in my next project I think it will be fun to learn F# in addition to C# and use both languges in the project.  To this end I just ordered Expert F#.  Knowing /prog/ is infinitely more expert then me: 

what does /prog/ think about .net?
what does /prog/ think about F# (ocaml)?
What type of tasks are better to be performed in F# vs C# (Math type tasks heavy)?

>>20
By your logic, >>12 is ultimately incorrect, since it's impossible NOT to know anything about something; Because you will know that you don't know anything about it.
That logic doesn't work, and you're wrong. So is >>12 for different reasons.
