If you add Configuration1, and then Configuration2, any properties shared will mean that Configuration1 will be returned. You can add multiple different types or the same type of properties file. If Configuration1 doesn't have the property, then Configuration2 will be checked. author:    Eric Pugh author:    Henning P.
