Question

I want to save some settings on a config file for future use.
I’m trying to use the regular code that I see on all the tutorials –

 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
 config.AppSettings.Settings["username"].Value = m_strUserName;

 // I also tried - 
 //config.AppSettings.Settings.Remove("username");
 //config.AppSettings.Settings.Add("username", m_strUserName);

 config.Save(ConfigurationSaveMode.Modified);
 ConfigurationManager.RefreshSection("appSettings");

Now – I can see that on runtime – the file “…vshost.exe.config” on “Debug” folder is changes, nut when I close my application – all the changes are deleted.
What can I do?

Answer 1

To test using the normal exe’s config file un-check the box for “Enable the Visual Studio Hosting Process” in the “Debug” tab in the project properties menu. That will make visual studio no-longer use the vshost.exe file to launch and the correct config file will be used.
