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)?

The faggots on /prog/ don't know enough to make informed decisions. They love old out-dated shit like C and C++. Yet they fail to realize C++'s default of passing objects by value is:
A. Fucking retarded
B. Not very object oriented
Passing object by reference is the rule, not the exception. But C++ fails to recognize that because its old and was designed to solve problems from decades ago.

/prog/ hates .Net solely because its Microsoft with no actual and factual complaints. Trust me, I have asked and not one /prog/ nigger can give significant cause to say .Net sucks.

.Net is actually one of the best and most complete development frameworks to come around in a long time. /prog/ is too busy reinventing the wheel with each app to appreciate something like a world class garbage collector, complete libraries, complete documentation and support from knowledgeable programmers.

As far as F#, it depends on what problems you think it will solve. What are you looking to get out of it that you can't get in C#?
