Where can I get the VSDoc for jQuery 1.4.2?
For the time being you could always just rename "jquery-1.4.1-vsdoc.js" to "jquery-1.4.2-vsdoc.js" and when they release the new vsdoc version just replace it.
Note: I had to then modify the script source path and then change it back again to force vs to pick up the vsdoc. I just added a forward slash at the start of the src attribute value and then removed it.
