Design patterns

[brunojuliao]

How you learned it and what book or course can you indicate?

[Krzysztof-Cieslak]

Again, F# For Fun and Profit is great resource. Additionally any talks by Scott Wlaschin and Mark Seemann are amazing and focus on "design patterns" and structuring F# applications.

Also, in principle, following general FP rules - building small, composable, pure functions and modeling domains with more powerful than C# type system, automatically leads to good design.
