Common app.config for multiple applications

Question

I have several C# console applications, which need to have the same set of settings. I want to avoid duplicity and avoid separate app.config for each applicatio

You can load an external app.config using the code below:

config = ConfigurationManager.OpenExeConfiguration(Path.Combine("C:\test\root", "Master.exe"));
string logpath = config.AppSettings.Settings["Log.Path"].Value;

And save settings as so:

config = ConfigurationManager.OpenExeConfiguration(Path.Combine("C:\test\root", "Master.exe"));
config.AppSettings.Settings["Log.Path"].Value = "C:\newpath";
config.Save();

You might have to have a master config within one of the applications and point the rest to this. Typically this method is considered bad practice though. There might be issues with different applications locking the file.
