Question

How would I share configuration data between .net desktop apps? I have used a common .ini file before but now when transitioning into .net I wonder if that’s the preferred way any longer? App.config seems more like an application specific file more than a common config file and I don’t know how to write settings there as ConfigurationManager.AppSettings.Set(…) seems not to actually write any changes.

Answer 1

It is possible to redirect configuration section to an external file via configSource attribute,

So you can put common settings in such a file, and load it in several app.config files.
