Commented Issue: nuget.exe update doesn't work on websites [1394]

Not sure if we even can do this but Anton asked for it :)

1. with a website (not a webapp) created in VS : install some packages
2. nuget.exe update says it can't find a project

e.g.
nuget update packages.config -RepositoryPath "C:\Users\aldion\Documents\Visual Studio 2010\Projects\WebSite10\packages"
Unable to locate project file for 'C:\Users\aldion\Documents\Visual Studio 2010\WebSites\WebSite10\packages.config'.
Comments: a fix for this will be really appreciated
