Patterns and Match Expressions in F#

Posted By: Kathleen McGrath | Jul 6th @ 7:58 PM | 30,582 Views | 7 Comments

In this video, programming writer, Gordon Hogenson explains and gives examples of patterns in F# and explains the use of the match expression to control branching based on patterns in data. But first, a disclaimer Gordon wanted to make: “Regrettably, I have not been able to retrain myself yet to use the word value instead of variable. In F#, all values are immutable by default, so it’s not really correct to use the term variable, as I do in the video.”   See Part 2 of this video: http://channel9.msdn.com/posts/kmcgrath/Active-Patterns-F/

Ok, I'm a great fun of F# as well as IronPython. Besides what he is talking about, i feel his coolness and geeky just because he speaks about F#! Great topic! So cool that he uses glasses!

A righteous infliction of retribution manifested by an appropriate agent.

It is great to have some F# videos that are encoded at the higher resolution, so that one can actually see the syntax.  

Having a language that can be run interactivly really helps with trying to demonstrate basic constructs, when you are trying to teach people how to use it.  

I thought that this video / interview was well done.

Speaking of patterns and matching, how do you search for "F#" on Channel9?  I get "Search term too small"...

Yes I don't like Microsoft naming; it can be hard to search for F#, C#, .NET

You can search for "FSharp" and "CSharp".  Videos are also tagged, so that you can easily find all videos created for a certain technology. For example, you can click on the FSharp tag in this post (http://channel9.msdn.com/tags/FSharp/) for F# videos.
