If you come from a C# background, this book is excellent: https://www.manning.com/books/functional-programming-in-c-sharp https://www.manning.com/books/functional-programming-in-c-sh... It does have some minor shortcomings in my opinion (e.g. if you haven't already started on the path of reinventing monads yourself you may struggle to immediately understand why this is a big deal and how it will save your life, the author should have used LanguageExt instead of their own library as LanguageExt is actively maintained and extremely well thought out, the book stops just short of becoming practical in the sense of "here's how to start a new C# project while thinking in functions", etc.). You might also consider the LanguageExt guide itself: https://github.com/louthy/language-ext/wiki/Thinking-Functionally https://github.com/louthy/language-ext/wiki/Thinking-Functio...
