I am creating a program that consists of a (1) Windows Service and a view (2) WPF Application. (the view and service do not have to be run at the same time) I will like to save all the settings on the same location. I was thinking to save all the settings on my application data directory. Because (1) and (2) are run by different users, Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) returns a different directory for each. How can I save both my wpf and windows service data on the same directory?

When I initialize my wpf application I will like to read some of the files created by my windows service. where should my windows service write files so that my wpf application can see them?

  • It's quite unusual to have a Service and a Desktop run on the same machine - in the corporate world this would be a no-no. So you'd need shared storage: either a network disk they can both access ot a database somewhere. – simon at rcl Mar 19 '14 at 18:08
  • It's not unusual at all. In our project, we take advantage of the fact that the service can be run at a higher elevation (Local System) than the application, which is generally restricted to user-level permissions. – Matt Davis Mar 19 '14 at 18:21
  • I know I can create a WCF service but that will waste memory create more work form me where I just need to read a license key file when my wpf application starts. – Tono Nam Mar 19 '14 at 18:24

You want CommonApplicationData, instead, the "common repository for all application-specific data that is used by all users," as MSDN puts it under SpecialFolder.

However, there are at least some cases where permissions conflict, so make sure the ACLs are set correctly.

This sample code may help.
