• Sung M Kim .net 2.0 problems

  Whenever I try to use anything from the 2.0 framework I get an error in VS2005. If I have "using System.Windows.Forms.VisualStyles;" The compiler tells me "VisualStyles" is not part of the System.Windows.Forms namespace.

  All the help stuff I have read, mentions using the command line InstallUtil.exe to do a service installation, followed by a manual start. Is it possible to have the service exe itself do the install and start-up to make distribution and handling a bit easier for non-techies (after all, users are used to just double clicking an exe file to have an app run, and it would be good to have the same functionality with a service.)
