How to register custom file extension to JavaScript editor in Visual Studio 2010/2012?

Question

(Also refer the original post on MSDN)

I have a very simple requirement which is to edit my own file extension (eg xsjs, xsapp...) with JavaScript editor in Visual Studio 2010/2012. Of course, these file extensions are fully ECMA standard compatible.

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 figure below) and applied changes. But it didn't work for any of the registered extensions.

Am I missing something here? Any one tells me how to do that?

Answer 1

1. Script editor is what you need. Afaik, there is no "javascript editor".

2. It's working for me. can you please explain what do you mean by "didn't work"

Answer 2

It's not currently possible to do it in any version of Visual Studio. I just got confirmation from http://connect.microsoft.com/VisualStudio/feedback/details/748574/cannot-register-custom-file-extension-to-javascript-editor-in-visual-studio-2010-2012 I'm considering to use other editors (eg Eclipse) to accomplish the task.
