Last night, I had the opportunity to present to the Microsoft Maniacs meetup in Sterling, VA. I want to thank everyone who attended, and share my slides and code. The slides are embedded above, and also included in the Github repo for my presentation, which is linked below.
It’s always frustrating when you’re working on a project, and everything looks good when you’re running it from Visual Studio, and then you deploy to your web server, and suddenly something’s not rendering correctly. In this post, I’ll give you some tips for troubleshooting these problems when the target browser is Internet Explorer.
Kristy Moon talking about MVC with Style
Stuart Leitch talking about async features in VB and C# (and a bit on Windows 8)
That’s quite a lineup, and I’m wishing I could make it for the meeting (Dane Morgridge and I will be recording a new episode of the Community Megaphone Podcast that evening), but if you’re available, I would strongly suggest making it out for this meeting.
And a bit of speaker trivia…Kristy Moon, who was one of the wonderful volunteers for last year’s inaugural MADExpo conference, volunteered her talents this year to give our website a fresh new look for MADExpo 2012. Personally, I think it looks great.
Don’t miss this opportunity to learn from three of the most talented folks I know in the Mid-Atlantic!
[This is the second in a 3-part series. Part 1, “Make Script Performance Automatic with Custom Templates in Visual Studio 2010”, can be found here.]
In part 1 of this series, I showed you how you can improve the script performance of your websites by using Visual Studio’s built-in support for exporting templates to create a new MVC3 web site template that relocates <script> references and blocks to the end of the page, where they will not interfere with the loading of the main visual elements of your site.
In this second part, I will show you how you can customize the T4 templates used to create new items in an MVC3 project, so that when you add new views to your project, they also have the scripts located at the end of the page. That way both the Master page / Layout for your original project AND any views you add have the scripts in the best location for performance. As a reminder, if your scripts dynamically add content to the DOM, you may want to leave those scripts in the <head> section of the page, since locating them at the bottom of the page may impact the page visibly during rendering.

If you’ve ever used a tool like Yahoo!’s Yslow to analyze the performance of your web application, you’ve probably run into the recommendation that you should put your scripts at the bottom of the page, unless those scripts insert page content (a good example of this, which we’ll see later in this post, is modernizr.js, which dynamically adds support for semantic HTML5 elements to older browsers that do not natively support them).
Unfortunately, if you use the default MVC 3 templates in Visual Studio 2010, things like the script reference for jQuery are added in at the top of the page, in the <head> section of the document. This works fine, but may potentially delay the loading of the page while the external script is downloaded and loaded. You could, of course, manually move the script references each time you create a new project, but this would result in unnecessary duplication of effort.
