I am getting CUBEPROGRAMMER_ERROR_NOT_SUPPORTED when I try to connect to a device

[MSSloan1962]

I am getting CUBEPROGRAMMER_ERROR_NOT_SUPPORTED (-5) when I try to connect to a device using connectDfuBootloader from STM32CubeProgrammer API v2.7.0. I am logging all the messages I am seeing and I have attached the log to this question. Does anyone know what I'm doing wrong or not doing. The C++ example seems to work fine. I am trying to write a C# application.

Hello @MSSloan1962​ ,

Please try to use latest release of STM32CubeProgrammer (version 2.11.0), as it contains updates to fix limitations. Then confirm if the problem here still existing with this version.
