C# 3.0 and the LINQ Project

In LINQ, we can group data using the "group by" clause. However, there are other potentially useful implementations of grouping. For example, we may want to group only adjacent elements or group ascending or descending parts of the data. This article shows how to use custom behavior when grouping data using "group by" in LINQ query.

Just a short update regarding the book I'm working on. First of all, the source code for the first 11 chapters is now available! Secondly, I did some changes to the TOC and you can now find the commented TOC on the book web site.

This article is partially an excerpt from my book. It introduces the benefits of functional pogramming, and explains the essential aspects of the functional style using F# and C# 3.0. Finally, it also shows how functional style influences the application architecture.

In this article, we'll implement a simple iteractve game using the Reactive LINQ project. The article shows that this way of handling events gives us amog other things a great degree of composability.

In the previous article, I introduced Reactive LINQ. Today, we're going to look at other operators that canbe used for working with events. We'll see aggregation is useful and how to dynamically change (switch) behavior.

In the second part of the series about reactive programming, I introduction the Reactive LINQ project, which allows writing event processing code in C# using LINQ queries.

The LINQ project and changes in C# 3.0 are interesting because they allow implementing many ideas from functional languages in C#. In this article I'll explain "first-class events" in F# and later I'll implemet similar concept using LINQ.

About a year ago, I wrote an article about infinite sequences on MSDN. I remembered about it this week, because these topics will be discussed in the book I'm working on as well...
