MonoTouch and F# that would be a cool duo right? Well let me explain what needs to be done and why to get this pair working together. I heard rumours a while ago that F# and MonoTouch would not play together nicely because of limitations in the ahead of time compilation (AOT). So I thought I would either prove or disprove this with some concentrated hacking. How hard can it be? As my good friend and colleague Dr. Kewin would quote: “No problem can withstand the assault of sustained thinking[...]

  Twelve F# type providers in action, brought to you with love by the Visual F# team and the F# Community Click on the images to learn more about using and/or contributing to the type providers. All your types are belong to us :)                                        

Thursday night (31 Jan) at the F#unctional Londoners Meetup we have Zach Bray telling us all about FunScript, aka "F# to Javascript, the FunScript way!" This includes a cool integration of TypeScript metadata into F#-JavaScript programming using an F# type provider for TypeScript. Another way to look at that is that all those TypeScript programmers are now producing typed components for use from F# too :-)  All your types belong to us. Thanks guys!! FunScript lets you connect to Web APIs like Freebase and [...]

Phil Trelford recently released Foq, a small F# mocking library (with a very daring name). If most of your code is in F#, this is probably not a big deal for you, because the technique of mocking isn’t very useful in F# (at least in my experience). On the other hand, if your goal is to unit test some C# code in F#, then Foq comes in very handy. So why would you want to write your unit tests in F# in the first place? Let’s start with some plain old C# code, like this:namespace CodeBase { using System; [...]

.Net 4.5 introduced a handy little new method Comparer<T>.Create to aid the creation of bespoke comparers, which is great because it means that you don’t have to define a new Comparer class when it is going to be needed once. In case you’re wondering, it’s still not possible to define anonymous implementation of interfaces in [...]
