• Functional Programming Tutorial for Visual Basic 9.0

  Visual Basic 9.0 added many language features that allow us to write in the functional style in a natural and expressive way. The value of programming in the functional style has been apparent to me for some time, and VB developers can realize the same benefits as C# developers, so I’ve written a tutorial for VB developers: Query Composition using Functional Programming Techniques in VB 9.0 . This tutorial is a rewrite of a tutorial that I wrote in the early part of 2008, Query Composition using Read More...

• Object Dumper: An Invaluable Tool for Writing Code in the Functional Programming Style

  When developing C# programs in the functional programming style, you often need to dump out a collection to the console. Object dumper is a great tool to use for this. It is a sample that far too few developers know about. A functional transform typically takes the form of successive transformations: transform collection a => collection b => collection c => final collection. This is one of the main points of this topic in my Functional Programming Tutorial . When I commence developing such Read More...

• Are Developers Using LINQ? (Part 2)

  The response to my previous blog post has been very interesting to me. And it has, to a very large extent, matched my own experience. I have seen four basic scenarios where folks use LINQ: Using LINQ to Objects (and LINQ to XML, which is really just LINQ to Objects), primarily using the extension methods, and the so-called ‘method syntax’. This really is a great scenario. When I really understood it, it blew my mind. I believe it leads to the possibility of “speed-reading” code – see below. Using Read More...

• Are Developers Using LINQ?

  I had an interesting conversation with my nephew the other day. He is a very bright CS student working as a summer intern at a software company (not Microsoft). He is programming in C# using Visual Studio 2008. I asked him if developers at his company were using LINQ, and he said, "No, that the folks in charge had basically forbidden it, because no one understands it." Visual Studio 2008 has been out for over a year, but I know that a fair number of competent developers have not devoted the time Read More...

• Using Annotations to Transform LINQ to XML Trees in an XSLT Style (Improved Approach)

  In our family, we have a rule – on Mother's day, my wife basically gets to set the agenda for the entire weekend. And, as appropriate, she doesn't have to lift a finger around the house. And on Father's day, the same rule applies for me. But on all other weekends, normal rules apply. This year, because my wife was out of town on the actual Father's day, we shifted Father's day to this last weekend, and my choice for how to spend the weekend was to write the code that I'm presenting here, and to write Read More...
