    // SecurityTreatAsSafeAttribute:
    // Indicates that the code may contain violations to the security critical rules (e.g. transitions from
    //      critical to non-public transparent, transparent to non-public critical, etc.), has been audited for
    //      security concerns and is considered security clean.
    // At assembly-scope, all rule checks will be suppressed within the assembly and for calls made against the assembly.
    // At type-scope, all rule checks will be suppressed for members within the type and for calls made against the type.
    // At member level (e.g. field and method) the code will be treated as public - i.e. no rule checks for the members.
