BUG: IsOffline is readonly in .NET2.0 / VS2005

This property is readonly in version 2.0 of the .NET framework. To force offline, you must use an ambient property. One workaround is here: https://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=817004&SiteID=1. Another workaround (in Russian, I'm afraid) is here: http://iamnik.livejournal.com/16380.html
