Question

We have the beginnings of a modular wpf application built using prism.

We want to allow for each module to have specific configuration – app settings / connection strings etc.

We’ve currently got things working by specifying all configuration in the shell project as a short term fix. Clearly this breaks the modular approach we are looking for – can anyone point me in the right direction?

Thanks.

You can try to rename app.config for every specific module to something like YourModule.Name.config and load that file in your module with code like:

var filename = Assembly.GetExecutingAssembly().Location;
var configuration = ConfigurationManager.OpenExeConfiguration(filename);
if (configuration != null)
    _setting = configuration.AppSettings.Settings["SettingName"].Value;

Maybe you should play some with filename (like adding .config in the end), I can’t check it right now.
