upgrading visual studio integration to use 6.8.2....

Hi Krasimir,

Yes, I'm sure that's true.  I suspect the best way is for Visual Haskell to 
  add its own configuration sections to the .cabal file, and recognise them 
when they are already there.

Understanding the .cabal file is not a problem, but we also have to be able 
to modify it, for example when the user adds a module.  In the presence of 
configurations this could be tricky, but for the complex cases where we 
can't figure out how to modify it we can just require the user to edit the 
.cabal file by hand (since presumably it wasn't generated by Visual Haskell 
in the first place anyway).

BTW, I was recently made aware of "Visual Studio Shell":


This is a freely redistributable Visual Studio installer that includes no 
language support, but allows plugins.  In theory at least Visual Haskell 
ought to run on top of it.  So then a complete Visual Haskell would be 
available for free.  Are you (or anyone else) interested in looking into this?
