The Functional Language Microsoft Built - Now with AI Superpowers
F# is the best-kept secret in the .NET world. It gives you full access to ASP.NET Core, Azure SDKs, Entity Framework, and over 300,000 NuGet packages - while bringing the elegance, safety, and testability of functional programming that makes your code dramatically easier to reason about and maintain. F# Programming with AI is your complete guide to mastering it, from your first immutable variable to building five production-grade, AI-powered applications.
In 2026, as AI workloads and data pipelines dominate backend development, F#'s composition model, strong type inference, and computation expressions make it uniquely positioned for intelligent systems. This book teaches you both the language and how to use it to build backends that think.
What You'll Learn:Organized across four progressive parts - F# Foundations, Intermediate & Advanced F#, AI & Modern Development, and Real-World Projects - the book takes you from a single printfn to deploying cloud-hosted, AI-integrated systems. Six appendices deliver quick references for F# syntax, the dotnet CLI, NuGet packages, discriminated unions, AI integration checklists, and a recommended learning path.
By the end you will have built a functional task management system, an AI-powered chat assistant, a smart analytics dashboard, a recommendation engine, and an AI-assisted data processing platform - all in F#.
Perfect For:The power of .NET. The elegance of functional programming. The intelligence of AI. Start with F# today.
