ASP.NET Ajax 3.5 SP1 contains a new feature that enables the application developer to combine scripts in order to reduce the number of downloaded files. But in order to do that, the developer must have a way of discovering what scripts are being used in a page or application.
To make that easier, I've developed a small control that you can drop onto a page and that will render out the list of script references that are being used by the page. It is then easy to copy and paste that list into the CombinedScripts property of the script manager and combine all those references into one.
The control also renders two links that enable the developer to download the debug and release versions of the combined scripts. Those scripts can be downloaded, copied into the site and used with the Path property on CombinedScripts. This enables better server performance than the plain automatic combination that ScriptResource.axd performs, but it also means you need to re-generate that file every time any of the scripts change.
The project to build the control can be downloaded as part of the ASP.NET CodePlex project:
UPDATE: the component can also be downloaded in binary form from here:
