"Lately, I have been playing with few JavaScript frameworks and in today's modern web applications it is very common that we are including tons of JavaScript files in our application. One of the thing that plays important role in application performance is how fast these script files are delivered into the browsers. I have extensively blogged on combining, compression and caching of JavaScript files in my old blog, in this post I will show you, how you can achieve parallelism in delivering the scripts in the browser with the Head JS library. If you do not know what parallel script downloading is and how does it impact on page speed, then I would suggest to read this article of the YSlow creator. In short, when a browser encounters a script tag in a page it halts its rending until it downloads the script file, the parallelism is actually archived by adding the script dynamically or by XHR depending upon the browser it is running."

Using Visual Studio symbols and source files makes debugging much easier. I am specially happy about ASP.NET MVC 2 source files because I develop on ASP.NET MVC 2 almost every day. You may also find other useful symbols and source files. In this posting I will show you how to get ASP.NET MVC source to your computer and how to use it.

"The primary issue with running an ASP.NET site in IIS7 Integrated Pipeline mode is if you have any HTTP modules configured. See, the "problem" is that with ASP.NET under IIS6, there were essentially two pipelines: one for ASP.NET and one for IIS. A request would come into IIS and if the file extension was mapped to the ASP.NET ISAPI extension, the request would be passed off to aspnet_isapi.dll and was then processed by the ASP.NET pipeline, which is where the HTTP modules come into play with regards to events that occur in the pipeline. However, in IIS7 there is only one pipeline for those events, and its used for both IIS7 native modules and ASP.NET modules (once the pipeline events have been taken care of, the file is taken care of by the appropriate ISAPI extension)."

"Optimizing application performance is a key element for business. There are several ways by which we can optimize the applications performance. It can be done either by server side code optimization, caching or some client side optimization. In this post I am going to discuss about one handy and smart way to optimize web applications performance using Bundling and Minification features which is introduced with ASP.NET 4.5 Developer Preview. ASP.NET 4.5 Developer Preview introduced bundling, which combines multiple JavaScript files for faster loading with less number of requests for download and minification, which reduces the size of JavaScript and CSS files by removing unneeded characters . Combination of these bundling and minification helps web pages to load very faster. Let's have a looks how it works."

"ASP.NET MVC 3 introduced global filters, which allows you to add the AuthorizeAttribute filter to the global.asax file to protect every action method of every controller. (In MVC versions prior to MVC 3, it was difficult to enforce the AuthorizeAttribute attribute be applied to all methods except login/register. See my previous blog on security for details.) The code below shows how to add the AuthorizeAttribute filter globally."

"You cannot use routing or web.config files to secure your MVC application. The only supported way to secure your MVC application is to use a base class with an [Authorize] attribute, and then have each controller type subclass that base type. "

One of the things my team has been working on has been a new view engine option for ASP.NET. ASP.NET MVC has always supported the concept of "view engines" - which are the pluggable modules that implement different template syntax options. The "default" view engine for ASP.NET MVC today uses the same .aspx/.ascx/.master file templates as ASP.NET Web Forms. Other popular ASP.NET MVC view engines used today include Spark and NHaml. The new view-engine option we've been working on is optimized around HTML generation using a code-focused templating approach. The codename for this new view engine is "Razor", and we'll be shipping the first public beta of it shortly.

"A new ASP.NET MVC project includes preconfigured Membership, Profile and RoleManager providers right out of the box. Try it yourself - create a ASP.NET MVC application, crack open the web.config file and have a look. "

Looks like I'll be using this one. Seems to be a bit better documented.
