    }

the communication starts and seems ok. But if I do await zvtClient.RegistrationAsync( rc ) or if I comment it out and it comes to var res = zvtClient.PaymentAsync( sum ).Result; the call will never come back.

Good morning to you. For me, the code you posted does not seem to be implemented quite correctly. But we do not provide free support here. But you are welcome to ask for paid support.

[obelixA]

The code is adapted from the examples on GitHub. If it is not correct, can you provide a working example, please? Thanks in advance Achim

The problem should now be solved after our joint analysis
