How do I create a taskpane in a c# project without VSTO? could someone point
me to sample code / article? I have seen many sample code using VSTO. but my
dll is not a VSTO addin and I want to create a taskpane and load my taskpane
in Excel.

OR, is it possible to create a docable window and doc it in excel? ( the
same you can doc a task pane into the ribbon area?)

please help.
