Enabling the ASP.NET Ajax script loader for your own scripts
In previous posts, I’ve shown different ways to build a client-side class browser, using the ASP.NET Ajax Libary and jQuery. -
JavaScript class browser: once again with jQuery
I’ve already posted twice about that little class browser application. The first iteration was mostly declarative and can be found here:

How to render the same template on the server and client with minimal redundancy
Last week, I wrote a post about how the new Microsoft Ajax Library Preview 6 made it a lot easier to write unobtrusive and imperative data-driven applications. Because for the previous preview, I had written a cool little class browser using a declarative style, I thought it would be nice to rewrite this in a completely imperative way. The mistake I made though was to call it unobtrusive. Never mind that ‘unobtrusive’ is a perfectly well-defined word that actually existed way before JavaScript. ‘Unobtrusive JavaScript’ has a very specific meaning that people feel strongly about. To be worthy of that label, an application must basically conform to (at least) those two requirements:

Entirely unobtrusive and imperative templates with Microsoft Ajax Library Preview 6
Today is the release of the sixth preview of Microsoft Ajax Library. Don’t get fooled by the somewhat silly and long name: this is a major release in many ways. The scripts have been majorly refactored since preview 5. Check out the other posts out there (links at the bottom of this post) to see just some of the many new features that are in there. Some of my favorite are all the small improvements that have been made to make imperative instantiation of components and templated contents easier than ever. Many of you have told us that you preferred to do things imperatively and this release makes it a lot better. -
Fun with C# 4.0’s dynamic
There’s been some debate recently on the new “dynamic” keyword in C# 4.0. As has been the case with many features before it, some love it, some hate it, some say it bloats the language, yadda yadda yadda. People said that about lambdas. Me, I’ll just use it where I see a use case, thank you very much. -
querySelectorAll on old IE versions: something that doesn’t work
In today’s post, I’m going to show an interesting technique to solve a problem and then I will tear it to pieces and explain why it is actually useless. I believe that negative results should also be published so that we can save other people from wasting time trying the same thing. So here goes… -
Mandelbrot set in a twitcode

Why is ASP.NET encoding &’s in script URLs? A tale of looking at entirely the wrong place for a cause to a non-existing bug.
Several people have reported seeing errors in their logs that seem to be due to requests such as this: -
Survey: Ajax usage among .NET developers
If you haven’t already and you are a .NET developer, please take a couple minutes and answer this survey, whether you use Ajax or not. There are a number of Ajax surveys around, but Simone’s is the only one that focuses on .NET developers. -
setInterval is (moderately) evil
JavaScript has two ways of delaying execution of code: setInterval and setTimeout. Both take a function or a string as the first parameter, and a number of milliseconds as the second parameter. The only difference is that the code provided to setInterval will run every n milliseconds whereas the code in setTimeout will run only once.
