I see it on the project source directory (not for solution).
I cannot see it on the release directory.
Is there any convention to read / write from app.config :
I want to use it for main application (connectionString for mySql).
When calling another exe file from the main application - should I pass the
connectionString as a parameter,
or it is preferred that each project has it's own app.config, and not pass
parameter trough?
