"MissingApplicationCertificate" Event is not being raised
Posted: 03 Sep 2022, 16:01
Hi Team,
In my custom C# console App (.Net Framework) (using the evaluation license), the MissingApplicationCertificate event is not being raised.
I have used License and App.Config files from GettingStarted sample project. I have also copied the Opc.Ua.CertificateGenerator.exe into the application output directory .i.e. next to the application exe.
The App.config file mentions below:
When I delete all available certificates from %CommonApplicationData%\unifiedautomation\UaSdkNetBundleEval\pkiclient\ location, I can see the MissingApplicationCertificate event being raised in the GettingStarted sample project . But when I do the same in my custom App, It does not raise it. I am testing in debug mode with breakpoints shown below. PLEASE HELP.
Below is my code:
