I am very pleased to report that a vision of the future of C# and Visual Basic was outlined today where they are moving to join F# in offering what I call language-integrated asynchronous programming support . This was outlined today at PDC10 by Anders Hejlsberg , the designer of C# and Technical Fellow...

[ The draft was updated on 22/10/10 and 8/11/10 ] The F# asynchronous programming model dates to 2007, and was published in product documentation and Expert F# . However, until now we haven't had a submitted, succinct conference-style description of the core idea of the model: language integrated...

In part 3 of this series, we explore lightweight , reactive agents in F# and look at some typical design patterns associated with these agents, including isolated internal state . Part 1 describes how F# is a parallel and reactive language with support for light-weight reactions, and gives patterns...

There is an F# tutorial and an F# talk today at TechDays, Paris , presented jointly with Adam Granicz and Robert Pickering.

I'll be giving a seminar tomorrow, Tuesday, at Berkeley, visitng Benjamin Hindman and Rastislav Bodik. The talk will be from 1:00 pm to 2:00 pm - room 320 in Soda Hall (moved from room 511). All welcome! Title: Parallel and Asynchronous Programming with F# Abstract: F# is a succinct and expressive...

In this post we will look at a common async design pattern I call Reporting Progress With Events . Later in this post we use this design pattern to read a sample stream of tweets from Twitter. This is the second part of a series covering basic techniques in F# async programming . Some of the samples...

F# is both a parallel and a reactive language. By this we mean that running F# programs can have both multiple active evaluations (e.g. .NET threads actively computing F# results), and multiple pending reactions (e.g. callbacks and agents waiting to react to events and messages). One simple way...

In September 2009 I posted the slides and code for the F# tutorial at JAOO 2009 . I've now updated this tutorial code for the F# Visual Studio 2010 Beta2 release (with matching CTP release for Visual Studio 2008) . We've also added some more content and explanatory comments. For example, we've added...

One of my colleagues at MSR Cambridge, Satnam Singh , has written his very first blog entry, and what a beauty it is ! Data parallel multicore programming from F# targeting both CPU and GPU - what joy! Microsoft recently released a preview of the Accelerator V2 GPU and x64 multicore programming...

I've just discovered Julien's great blog series on algorithmic programming in F# , a very useful resource. And if that doesn't whet your appetite, he also has a series on food :-) Here are some of his recent posts: Technical analysis indicators in F# This is the first part of a series on...

The latest release of F# is now out! This is included in Visual Studio 2010 Beta2 , released today for MSDN Subscribers, with the matching release of the F# CTP for Visual Studio 2008 , and a compiler ZIP for Mono . The detailed release notes are here . (Note: general download availability of Visual...

(These notes apply to the F# October 2009 CTP update and Visual Studio 2010 Beta2 ) Summary Release F# in Visual Studio2010 Beta2 can build applications for .NET 2.0/3.0/3.5/4.0 and Silverlight 2/3. Updated F# CTP for Visual Studio 2008 F# PowerPack available as part of the CTP...

[ The attached tutorial code has now been updated for the F# Visual Studio 2010 Beta2 release (with matching CTP update for Visual Studio 2008) ] One of the great pleasures of my job is to go to conferences like JAOO and present on F# and other topics. This year I presented both a tutorial and a lecture...

I’m excited to be giving a tutorial, a presentation and a panel at JAOO 2009 in Aarhus in early October. I’ve had the good fortune to be involved with JAOO and QCon a few times over the last few years, and am honoured to be presenting in Aarhus, the home of it all. I’ve copied details below – hope...

The main announcement for this release is here . Summary Release F# is integrated into Visual Studio 2010 Beta1 F# in Visual Studio2010 can build applications for .NET 4.0 Beta1 Updated F# CTP for Visual Studio 2008 and .NET 2.0/3.0/3.5 F# PowerPack is a separate download for...

The F# team are thrilled to announce that Visual Studio 2010 Beta1 is now available , including the latest version of F#. Today we are also releasing a matching F# May 2009 CTP for use with Visual Studio 2008 ( MSI , ZIP ). Further below is a screen shot , more here . If you’re new to F#, consider...

The Maestro team are a Microsoft incubation group looking at Isolation, Agents and Message Passing on .NET. Niklas, from the team, has been very helpful as a reviewer of F# asynchronous workflows and whenever I'm in Redmond we get together to discuss associated topics. It's great to see the team get...

Matt has a lovely post showing how to define parallel sequences in F# : In many of my presentations lately, I’ve been using the Parallel Extensions for .NET as part of my heavy computations in F#. By doing so, I’m able to speed up some of my heavier computations by several fold and take full advantage...

Kean over at AutoDesk (think AutoCAD etc.) is running an F# programming contest ! I've included his post below: F# programming contest ... So to start 2009 with a bang (or a pop, at least) I'm going to run a programming contest. The basic idea is to generate some cool examples of...

Last year, the head of the Microsoft’s Developer Division, S. Somasegar, announced that Microsoft had begun investing in F# as one of Microsoft’s supported languages on the .NET platform. I am now thrilled to announce one result of this investment: F# will ship as part of Visual Studio 2010! Since the...

One of the most intriguing F# announcements recently is " Avalda FPGA Developer ". Here's the descripton from Stephen Afande , the brains behind Avalda: The compiler enables folks to compile [a subset of] F# code to an HDL netlist output suitable for running on an FPGA. From Avalda's home page...

Ralf Herbrich has updated both the TrueSkill in F# and TrueSkill Through Time samples to both work with the new F# September 2008 CTP and to use unit-of-measure with the Gaussian belief distributions. Ralf says: Following the publication of the F# source code for the TrueSkill Through Time...
