Dive into a comprehensive F# tutorial designed to equip programmers with the essential tools and best practices for writing functional F# code. Explore key concepts such as let bindings, type inference, functions, currying, partial application, and function composition. Delve into F#'s type system, including product types, sum types, and pattern matching. Learn about collections, exception handling, and error modeling. Gain insights into file organization, namespaces, and modules. Master F# Interactive, understand the differences between expressions and statements, and explore advanced topics like generics and statically resolved type parameters. By the end of this step-by-step guide, acquire the knowledge to be immediately productive in F# programming while avoiding common pitfalls.
