In this article, I explore the amazing relationship between functional data types and algebraic operations. We will use this relationship to reason about domain model and understand the differences between several possible representations.

This article is inspired by an MVP summit talk about common pitfalls in the C# asynchronous programming model. I look at a number of easy to make mistakes when writing asynchronous code in C# and demonstrate that most of them would not easily happen when using F#.

F# Data is a new library that gives you all you need to access data in F# 3.0. It implements type providers for WorldBank, Freebase and structured document formats (CSV, JSON and XML) as well as other helpers. This article introduces the library and gives a quick overview of its features.

After a few years, I will be attending the MVP summit again this year. The good news for those interested in F# is that I have two talks scheduled along the way in New York and Boston. Aside from that, we also have dates for a new F# course in London and New Year!

This article introduces a new F# package that makes it possible to write literate F# programs that combine code with documentation. Given an F# script with a special comments or Markdown document with F# code, you get a nicely formatted HTML that can be used to build documentation or write blogs.
