ConfigurationManager doesn't save settings to exe.config

Question

(My question is similar to this one, but the code is slightly different, and the solution doesn't work for me)

I'm trying to save settings changes to the app.config:

Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.AppSettings.Settings("HistoryRootDirectoryPath").Value = p_historySavingPath
config.Save(ConfigurationSaveMode.Modified)
ConfigurationManager.RefreshSection("appSettings")

Nothing is saved neither to the exe.config file in bin folder, and not to the actual app.config file. What am I doing wrong?

Are you getting any errors? Exceptions? Have you looked at both the `Debug` and `Release` folders? — Oded, Dec 15 '11 at 11:13
@Oded: Checked both debug and release, no exception been thrown. — MichaelS, Dec 15 '11 at 11:38
Ah. Because the code is being run under the Visual Studio process host. — Oded, Dec 15 '11 at 11:45

Finally ended finding the changes are being saved under .vshost.exe.config.

As Oded mentioned,that is because the code is being run under the Visual Studio process host.

Note that the changes are being reverted once you stop the process run.
