  • Building Functional .NET Applications: a Guide for Choosing between F# vs C#

    C# and F# are languages, each with growing user bases, that approach functional programming in fundamentally different ways. C# relies on object-oriented, imperative principles, and F# relies on functional principles.  Some developers are using F# as a complement to C#, rather than relying on the functional capabilities that exist natively in C#.

  • What’s New on F#: Q&A With Phillip Carter

    Last month, at the 2020 edition of .NET Conf, Microsoft released the latest version of F#. F# is as functional-first, cross-platform, open-source .NET programming language, and it’s developed by Microsoft and several open source partners and contributors. InfoQ interviewed Phillip Carter, program manager at Microsoft, to talk about functional programming, F#, and the new features of F# 5.

  • A Comprehensive Look at F# 4.1

    Semantic versioning can be misleading. While F# 4.1 is backwards compatible with F# 4.0, it is by no means a minor release. With both Microsoft and the larger community contributing, several more features were introduced since the F# 4.1 preview in the areas of performance, interoperability, and convenience.

  • Virtual Panel: What's Next for .NET?

    A lot happened in the last year in the .NET ecosystem. Putting aside the details, the bigger picture is difficult to grasp. There is movement in all aspects: cross-platform, cloud, mobile, web apps and universal apps. Developers wonder where all of this is going to lead and what will be required to get there.

  • F# in Numbers: A Look at the Annual F# Survey Results

    In April, for the second time, fsharpWorks organized the F# community survey. Over 600 developers completed the survey in 2016 (which is 15% more than in 2015). The survey provides an insight into the brains of the F# community. In this article, I'll summarize some of the results.

  • F# Deep Dives Review and Author Q&A

    F# Deep Dives, edited by Tomas Petricek and Phillip Trelford, is a new book aimed at showing what is the business value that using F# brings in practice. The book presents 11 real industrial scenarios and the way F# allowed field experts to solve them using a functional-first approach. InfoQ has interviewed Tomas Petricek, co-editor of the book.

  • Simplifying F# Type Provider Development

    Type Providers are an essential element for F#’s extensibility model, but creating new ones can be a chore. Dave Fancher shows how to take the tedium out authoring Type Providers using some simple inline factory methods.

  • The Book of F# - Review and Interview with Dave Fancher

    The book of F#, authored by Dave Fancher examines the concepts associated with F# with the help of comprehensive explanation and relevant source codes. Towards the end of the book, Fancher provides coverage of advanced topics such as asynchronous and parallel programming.

  • F# mobile development with WebSharper

    Functional programming languages can lead to novel ways of thinking about application development. There is just something about using a different paradigm that puts engineering problems into a new context. In such a spirit, Adam Granicz shows how F# and WebSharper can be used to tame mobile development.

  • Beyond Foundations of F# - Asynchronous Workflows

    Robert Pickering continues the conversation in this third article on F# and this time focuses on Asynchronous Workflows and the resulting peformance gains obtained when used. While this article focuses on F#, the learnings are applicable across .NET languages.

  • Beyond Foundations of F# - Workflows

    Continuing Robert Pickering's series of articles on F#, this InfoQ exlclusive article focuses on workflows in F#. Workflows are the building blocks for library implementers interested in the basics of DSLs.

  • Beyond Foundations of F# - Active Patterns

    Since Robert Pickering published Foundations of F# in May, the language has grown significantly. Besides adding a host of new features, it is being moved from a research project to a fully supported, production-grade release. We asked Robert to discuss some of the new features in F#.
