In the last post I discussed an asynchronous version of the ManualResetEvent and as promised this time we will be looking at an asynchronous version of the AutoResetEvent. I’m using Stephen Toubs post as reference and we will be building a version that is functional in style that maps straight into asynchronous work flows without and conversion or adaptors. What is an AutoResetEvent? An AutoResetEvent can be described as a turnstile mechanism, it lets a single waiting person through before re-latching [...]

In this post we are going back to the primitive. No it’s not about the same named song by Soulfly, (which incidentally does contains F# notes) but a return to thread synchronisation primitives and their asynchronous counterparts. We are going to be looking at an asynchronous version of the ManualResetEvent. This was recently covered by Stephen Toub on the pfx team blog. We will be taking a slightly different view on this as we will be using asynchronous workflows which will give us nice idiomatic usage[...]

In this edition we are going to be doing a taste test, C# vs F#. Oh yeah, if you quickly glanced at the title you may have thought this was a recipe for black scones, as interesting and tasty as that may be, unfortunately its going to be finance related. I recently presented a paper on the benefits of F#, part of this was a comparison of the famous Black-Scholes equation in both C# and F#. I was mainly going to be looking at code succinctness and the inherent suitability of the language for calculation [...]

This will be the last post on rebuilding the MailboxProcessor using TDF, here’s a quick discussion of the missing pieces… First, lets start with the simple ones, these don’t really require much discussion. DefaultTimeout 1 2 3 4 5 let mutable defaultTimeout = Timeout.Infinite member x.DefaultTimeout with get() = defaultTimeout and set(value) = defaultTimeout <- value This simply provides a mutable property using Timeout.Infinite as a default setting. CurrentQueueLength 1 member x.CurrentQu[...]
