Hello @Ido Ikar ,
the samples you use are based on this code repository: Azure SDK for Embedded C.
Recently, this Arduino library was announced based on the same SDK.
Next to that, check out the Nano framework. This is an exciting solution to program on various embedded devices, just using C#.
Regarding professional help, you reached the Q&A section of MS Learn which is a moderated community portal.
You can reach out to your local Microsoft representative and ask to get in contact with the global Azure IoT blackbelt team. If this is hard for you, as an MVP I can introduce you too.
