T_APPL_DATA_LN_N1 subtest 3 fails on an LN-only server regardless of the response to a non-existing-object GET

Forums
DLMSDirector

I'm testing an embedded LN-only DLMS/COSEM server with the GXDLMSDirector Application Conformance Test. 13 of 14 tests pass; the only failing one is T_APPL_DATA_LN_N1, and it always fails on subtest 3 ("Read non-existing object").

The tool sends a GET for a non-existing object (class 15 / Association LN,
OBIS FF FF FF FF FF FF, attribute 1):

C0 01 C1 00 0F FF FF FF FF FF FF 01 00

The overall result is always:

T_APPL_DATA_LN_N1 subtest 3 succeeded when Short Name referencing is used.
T_APPL_DATA_LN_N1 failed.

Version mismatch between Gurux.DLMS 9.x and Gurux.Common/Gurux.Serial 8.x

Forums
Gurux.Net

Hello Gurux Team,

I am developing a new Windows Forms (.NET Framework 4.7.2) DLMS client using the latest Gurux.DLMS.

My installed packages are:

Gurux.DLMS: 9.0.2605.2801
Gurux.Common: 8.4.2503.602
Gurux.Serial: 8.4.2503.603

I downloaded the latest Gurux.DLMS.Client.Example.Net from GitHub (Version 9.0.2605.2801), and GXDLMSReader.cs references:

using Gurux.Net;

However, I cannot find matching 9.x NuGet packages for Gurux.Common, Gurux.Serial, or Gurux.Net. Only 8.x versions are available.

Could you please clarify:
