One tool can not fit all needs.
Chris Smith’s on his Blog, says
” But just because you can write code in a new language doesn’t mean you should. So why use F#? Because being a functional language, F# makes writing some classes of programs much easier than its imperative cousins like C#. Parallel Programming and Language-Oriented Programming are two such domains that can be expressed easily in F#.
If you’ve ever written a .NET application and found yourself fighting against the language to get your idea expressed, then perhaps F# is what you’ve been looking for.”
F# is basically an functional language by its nature. The argument here could be more towards the style of programming rather than features a language may support.
As per Eric Lipert answer to a similar topic ( my post was inpired to ) at stackoverflow, following things are to be considered before one thinks about using F# as the language of choice for a project.
