Thanks, Ian and Roger for your swift reply.
I wondered why Paolo did not respond to my personal email to his
email address.
At the moment I have only tried to build my prototype program using
Sharpdeveloper, I did not try Visual Studio as well. Because I have
not installed Visual Studio on my Windows 10 PC.
I used Nuget to install the M2Mqtt package on my PC.
I'm using on another Windows 10 PC the Mosquitto broker. This broker
functions satisfactory using the paho-mqttv3.dll on from my
development PC to publish topics & payloads, also the Node.js
mqtt on a few raspberry PI's. And also I receive the mqtt messages
using a Groovy (Java mqtt jar) subscriber script, which updates the
message data into my oracle dbms.
I'm not sure what you mean by log files. In this concatenated email
there is information about a warning and error messages from
SharpDeveloper and differences AsmSpy found when inspecting the
m2mqtt assembly . Please see the bold sentences in the earlier
emails.

Jan,
Paolo started a new job recently, which will have impacted his
ability to answer questions. I'll try.
Are all your builds in SharpDevelop, or have you tried Visual
Studio as well? Did you build the M2MQTT library you are using,
or did you download it?
A MsgID value of 1 in itself, in MQTT, would not indicate an
error. What MQTT server are you using? Are there any log
messages on it that might indicate what is going on?

A
kindly request to this group: is there somebody available with
C# knowledge of the M2Mqtt library and who can answer my
questions, which I sent last week to this group?
At present I could build and run the prototype C# program
without runtime errors, but I get a MSgID of value 1 and my
Groovy subscriber did not recieve the topic and Payload message.
What does the value 1 of the MsgID means?
With best regards,

Hallo Paolo and pah-dev group,
On March, the 29th I sent you, Paolo, an email with some
questions about C# M2Mqtt client library in order to make a
start with a case study on the subject of using the M2Mqtt
library in a Winbatch script on a Windows 10 pro (64)
environment. A couple days later I also joined the paho-dev
mailing group following an advice form Dominik of HiveMQ.
unfortunately I did not get any answers on both emails.
In the meantime I started to develop as a first step a sample C#
program in order to get familiar with the library in publishing
a payload message, see the attached program.cs file.
When I build the program.cs in sharpDeveloper, I get the
following errors, which are in Dutch.
<code>
Build started.

The warning is about differences in reference to the used
assemblies in M2Mqtt.WinRT.dll. The tool AsmSpy gives the
differences as:
<code>

Reference: System.Threading.Tasks
4.0.0.0 by M2Mqtt.WinRT
Reference: System.Runtime.WindowsRuntime

</code>
How can I resolve this warning and the related errors?
Any tips or suggestions?
Thanks in advance,
Beste regards, from the Netherlands,
Jan Willem Teunisse

Ciao Paolo,
Last week I read your nice and clear article about the MQTT
Client library (M2Mqtt) and liked to try it for my domotica IoT
project.
I installed yesterday using Nuget the M2Mqtt dotnet library
package on my windows10 development PC in order to publish a
MQTT message using a Winbatch script.
Winbatch support dotnet assemblies. The M2Mqtt package is
installed in the Winbatch script directory using “nuget install
M2Mqtt -o D:\Winbatch\Ontw”
After installing the M2Mqtt package I saw 6 subdirectories in
the d:\Winbatch\Ontw\M2Mqtt.4.3.0.0\lib\ directory. All
containing different DLLs.
I’m now confused which DLL I have to take to get the
uPLibrary.Networking.M2Mqtt namespace and to define the object
new MqttClient.
Maybe you can help me out, as I need some suggestions or advice
to proceed from here on to get things working.
Beste regards, from the Netherlands,
Jan Willem Teunisse
P.S. I also posted a comment on the blog of the above mentioned
article, Dominik advices me to contact you more or less
directly.
