Newbie here. Somebody can point to useful other resources for F#?

https://fsharpforfunandprofit.com is great. I'm enjoying Don Syme's book "Expert F# 4.0" as well.

Asynchronous programming with F# is pretty cool. It has layered powerful syntax and language constructs on top of .NET's threads and tasks, AND it gives you convenient access to the same async API that you use in C#.

Is there a really good reason to choose to use F# over C#? Or does it really just come down to preference?

Ask HN: I've toyed around with F# and I kinda like it but I've never dug deep enough into it to answer the question: can I use this for 'real life' code as part of an existing C# desktop application for instance, e.g. build some F# into an assembly which is callable from C#? Without tons of hassle? What are good samples of real life application code in F#?

It depends if you enjoy NullPointerExceptions.

If you want to try out f#, don't forget to try it with http://fsharp.github.io/FSharp.Data/

It's pretty awesome

Yes. Your standard OOP features like inheriting from C# classes, implementing interfaces, etc are supported natively in F#. The main hassle in being C#-compatible is exposing an external OOP api with only .NET types and interfaces instead of standard F# types. This means, for example, exposing `seq` (`IEnumerable`) instead of `list` (`Microsoft.FSharp.Collections.List`) or using the struct-tuple construct in F# 4.1 so C# 7 can access it.

No personal recommendations but have you seen https://github.com/fsprojects/awesome-fsharp
