(Also see the original message on MSDN)
I have a very simple requirement: edit my own file extension (e.g. xsjs, xsapp ...) with a JavaScript editor in Visual Studio 2010/2012. Of course, these file extensions are fully compatible with ECMA.
When I came to Tools → Options → Text Editor → File Extension and added my own extension, there is no JavaScript editor at all :( Then I chose the most likely option “Script Editor” (see the figure below) and the changes made, but it didn’t work either for one of the registered extensions.
Am I missing something? Does anyone tell me how to do this?
