Question

I’ve searched the web (and evaluated books on online shops) but I’m not satisfied with articles found on the subject.

If you search the web with keywords C# and functional you find a lot of basics or Linq articles.

I’m also disagree with the first reply to this question:

Are the functional programming features provided in C# rich enough? What’s missing

After all F# is built on .NET (as C#) and is a functional language widely used and with good reputation.

Is there out a set of good articles, a book or even techniques explained here about good functional patterns that can be profitably used in C#?

As said I’m searching nor introductory material nor guides on specific technologies (like Linq, which I use and love).

I’d like also to hear if a particular technique can be safely exposed to a reusable library Public API (hope this not too off-topic).

Real-World Functional Programming: With Examples in F# and C# [Paperback]
Tomas Petricek (Author), Jon Skeet (Author)

Amazon Link

From the Amazon book description:

Real-World Functional Programming is a unique tutorial that explores
the functional programming model through the F# and C# languages. The
clearly presented ideas and examples teach readers how functional
programming differs from other approaches. It explains how ideas look
in F#-a functional language-as well as how they can be successfully
used to solve programming problems in C#. Readers build on what they
know about .NET and learn where a functional approach makes the most
sense and how to apply it effectively in those cases.
