Failures with release 7.2 under 4.7.2 and 4.8
Dear @vnau. I find your kelary.ivi.visa simply brilliant. Thank you. I used, I believe, a previous release (5.?) but it seems that the 7.2 release somehow blocks access to the resource manager.
I was getting the following error when running the IviVisaNetSample under .NET Framework 4.8:
VISA.NET Shared Components version 7.2.0.0.
VISA Shared Components version 7.1.6708.0 detected.
Exception: Failed to parse TCPIP0::192.168.0.144::inst0::INSTR
To explore this further, I compiled a program to query the instrument identity and added a resource lookup using the IVI.Visa global resource manager. I then compared the results using the current 7.2 release of the Kelay.ivi.visa package versus using a direct reference to IVI.Visa (5.11).
While using ivi.visa directly works, I am getting the failure to parse error when referencing the package.
Here are my results:
Failure running IviVisaSentSample (I added the name of the running framework).
