@HASSEN-MEDDEB-ATOS This is not the correct place to post this issue as there are no samples here related to the new (alpha) CDS service client. For assistance with this problem, go to the NuGet page for the package that contains the assembly/class in question and select the 'Contact owners' link on that page. That should get you a response.
