Microsoft Visual Studio 2008 AJAX Profiling Extensions is a new power tool to measure the performance of the portions of web applications that execute JavaScript inside the web browser.

S. Somasegar, Microsoft's Senior Vice President of Developer Division, has announced the tool in a posting on his blog, VS2008 AJAX Profiling Extensions.

He writes:

The AJAX Profiling Extensions provide much-needed visibility into often complex, web client-side interactions for the first time. You do not need to download and install any additional software, plug-ins, or ActiveX controls on the machine where the AJAX web client code is running to use the AJAX Profiling Extensions to gather JavaScript execution-time data. Also, this works with any web browser, including, of course, the latest version of Internet Explorer.

AJAX Profiling Extensions is an add-on to the performance tools that are available in Visual Studio Team System 2008 Development Edition and Visual Studio Team Suite, extending them to allow you to profile the client-side JavaScript code in your AJAX application.

For more information about Visual Studio 2008 AJAX Profiling Extensions, see VS2008 AJAX Profiling Extensions. To get started monitoring the performance of your client-side AJAX code, download Visual Studio 2008 AJAX Profiling Extensions from Code Gallery.
