We're getting closer to the next major release of F#: our first CTP release out of Developer Division. As a result, now is a good time for me to start talking about some of what I've been working on for the past few months: the F# project system. Over the coming weeks I'll describe some of the new-to-F# project system features we'll deliver in the CTP, providing a "sneak peek" at what's coming.

Marcus Nasarek did a nice comparison of Bash vs PowerShell in Linux magazine HERE. It is only 2 pages but he covers the key elements and has been very fair to it. I appreciate the fact that he took the time to clearly understand PowerShell.

This continues a short series of posts about getting started with PowerShell … with a few tips about things you can do to keep your PowerShell profile safe and organized. Your “profile” is the script that is automatically loaded when you start up PowerShell. Really, I should say that your profile is the set of scripts which are loaded by default when you start up PowerShell. “By default” because you can always skip loading them by passing the -NoProfile switch to PowerShell.exe, and a set because PowerShell does, in fact, attempt to load at least four scripts when you run it.

We are very excited to announce the release of a new developer tool from Microsoft, Source Analysis for C#. This tool is known internally within Microsoft as StyleCop, and has been used for many years now to help teams enforce a common set of best practices for layout, readability, maintainability, and documentation of C# source code.

With the April Refresh hot off the presses, I figured it was time to write a concise, 20-minute introduction to F#. The goal isn't to teach F#, but rather give a quick overview of the language and some of the things you can do with it. I’ll divide the 20 minutes into three parts: * Part I - A slow introduction to F#, explaining your first program * Part II – A brisk overview of the foundational types and concepts in F# * Part III – A quick sampling into advanced topics

We take a critical look at who people are assuming will use F# and who is actually putting their money where their mouth is when it comes to this exciting new technology. The results are surprising!

Project Euler is not the only website dedicated to mathematical puzzles. In fact, it started as a subsection of Mathschallenge.net, a website that now has more than 300 exercises, grouped according to their difficulty, which ranges from 1 to 4 stars. We'll use F# to solve these puzzles, starting from an easy one, that asks us to find the smallest multiple of nine containing only even digits.

If you ever need to distribute and use resources such as text or xml files in a class library, you can use embedded resources. Here's how..

This article discusses the delegate type and how it can be used to point to methods in the application which can be invoked at later time. This article demonstrates also the delegate ability to multicast and delegate covariance.

When developing networked applications that rely on a remote computer being available, it is important to be able to check that the other system is operable. Using the .NET framework's Ping class, an ICMP echo request can be sent for this purpose.

In recent years AJAX on the web has actually pioneered some interesting GUI concepts. I've always liked it when web sites pop-up with a central window that turns the background slightly darker and then ask you for some input. Then you type that input in and press an OK button and then you get a nice little barber pole animation to indicate it has gone off back to the server and is waiting for a reply for the next step

Flying Frog have just announced the launch of their F# for numerics library (beta release).

Discover anew why Visual Basic is one of the most successful programming languages in history by exploring some of the new features Microsoft added to Visual Studio and Visual Basic.

Matthew Podwysocki writes about his experiences learning F#. Useful links section.

I have written a library for using software transactional memory in F#. The library exposes memory transactions as a monad using F#’s new computation expression feature. It can be downloaded here.

Yes, Ruby and other dynamic languages are all the rage these days. Yes, using Extension Methods in C# 3.0 is overplayed. But you know what... I don’t care! So I’m going to show you an Extension Method that will bring a little Ruby-goodness to your hum-drum C# world.

X++ is Microsoft's object-oriented language with similarities to C++ and Java for MorphX, a platform for constructing complex accounting and business management systems. X++ includes a number of common SQL commands as an integrated part of the language. The memory management model is extremely simple: objects are created with a new operator. There are no explicit programmer-defined pointer data types, and there is no pointer arithmetic. X++ provides extensive compile-time checking, followed by a second level of run-time checking. The X++ garbage collector runs automatically; as soon as no references exist to a particular object, that object is deleted and its storage is reclaimed.
