ABSTRACT
The F# language delivers practical, enjoyable, and productive programming for the era of the cloud. At the core of F# is succinct, performant functional-first programming, compiling to both .NET and JavaScript, with cross-platform, open-source toolchains for those at home in either ecosystem.

In this talk I’ll describe how in F# 5.0 and beyond we are adding more magic right across the F# stack – keeping programming simple and correct yet delivering the features you need for maximum productivity:
• Added expressivity and performance for DSLs using F# computation expressions
• High-performance state machines and resumable code for functional DSLs for collections, tasks, asynchronous sequences, and more
• Improved package management integration in F# scripting
• Interactive notebooks and a wide range of other tooling improvements
• F# analyzers, e.g. for additional shape checking in AI tensor programming
• Turnkey programming stacks for the client, server, and full-stack programming
Join me for this walk through the latest in 2021 for F#

My main responsibility is the design and implementation of the F# programming language. I’ve also worked on the design of virtual machines, the C# language (being co-responsible for C# and .NET generics, and one of many contributors to C# asynchronous programming) and, indirectly, Visual Basic and other .NET languages.

As a researcher, my area is programming language design and implementation, with emphasis on making languages that are simpler to use, interoperate well with other languages and which incorporate aspects of object-oriented, asynchronous and parallel programming. I am interested in programming language perspectives on type inference, concurrency, reactivity, extensible pattern matching and language-oriented programming. I also work extensively with teams in the Microsoft Developer Division on other programming-related technologies.

Don is the primary author of Expert F#. In the past I have worked in formal specification, interactive proof, automated verification and proof description languages. I have a PhD from the University of Cambridge and am a member of the WG2.8 working group on functional programming. […]
