    Resolution Note:

    There is quite a bit of reflection being used in System.Xml and mono and il2cpp work differently here.
    In il2cpp in current project the error happens because TestIXmlSerializable.GetSchema() returns new object and does not set Id on it. Change method to return null and "success" is printed on screen.

    For mono, disable the stripping. You can't ship new games using mono anyway.
