Config.xml

[shers]

that is your "problem"

dlls cannot have xml settings files. The settings you create are compiled into the dll, which is why everything works on another machine without the config file.
Think about the logic of this for a second.. Dlls are supposed to encapsulate some common functionality. Ergo, why would they have settings? Everything they need should be provided at the time of calling.

You must be right.

Please see this link and read the section

This is for exe.

You'd be annoyed if you had to create an ini file specifying the source and destiantion path every time you used the file.copy command in the .net core dll wouldn't you?

So what's the solution?
