Using the Select LINQ query operator with indexes
Yesterday, Fred asked me if I could help him to convert C# code to LINQ. The solution may not obvious to find unless you know LINQ well. I will reproduce here the solution I gave Fred. Whether the LINQ version of the code is easier to read than the original one is arguable. The purpose here is more to show LINQ's Select query operator in action.

XAML markup formatting in Visual Studio
I'm using WPF these days, and so reading and writing a lot of XAML markup. As with any code or text, reading and navigation are made easier with a clean format. In my XAML files, I've been putting the XML attributes aligned vertically, below their XML element. It looks like this:

I'm not that much a fan of fluent interfaces, but in some cases they are well fit.

To var or not to var
C# 3.0 and VB.NET 9.0 introduced implicit typing. When you use anonymous types, it's required. The rest of the time, it's mostly a judgment call to decide whether to use implicitly-typed local variables or not.
An interesting discussion is going on about this on Jean-Paul S. Boodhoo's blog. See all the comments.

Google killed me
In March and April, Google made a big update to its search algorithm. This update, nicknamed "Dewey", hit many websites. The result for these websites being a drastic decrease in search results ranking. The rankings have even changed a lot over the last weeks, sites moving up and down in search results. This is known as the Google Dance syndrome.

LINQ in Action is for VB developers too
A frequent question we get about our LINQ book is whether it's been written for C# developers only. If you think so, you're making a mistake.

Ever wanted to see LINQ in action, visually?
It's not always easy to grasp and follow what's happening when a LINQ query is executed. Well, thanks to clever code by Jon Skeet, it's now possible to see LINQ queries execute in front of your eyes! At least LINQ to Objects queries that is.

Rethrowing exceptions and preserving the full call stack trace
Did you know that depending on the way you rethrow exceptions you may lose important information? There are already several blog posts that explain and demonstrate the difference between throw and throw ex. I'm realizing only now that none of the two solutions yields the complete call stack trace information!
