Extensions and workbench integration

[#1]

Do QlikView extensions objects work out-of-the-box with QlikView Workbench? I have no experience using QVWB, but as I understand it it opens a qvw file on a server and gets data from some objects of the document to integrate them in an asp.net web page, so it should be possible to access an extension object instead of a standard qlikview object.

Has anyone experience about integrating extension objects with the workbench? Does it add any constraints on the extension code?

I cannot really ad value to your question but I also would love to have some more documentation on Creating Extensions and custom ASP pages with the Workbench. Sample projects or tutorials would be useful
