I understand that qlik sense allow debugging by attaching visual studio to a process.
Reference: https://help.qlik.com/sense/en-US/developer/#../Subsystems/QVXSDKAPI/Content/Debugging your connector.htm%3FTocPath%3DQlik%2520QVX%2520SDK%7CAdditional%2520features%7C_____6
However I could not find the exact process to attach (have tried qliksense.exe, qliksensebrowser.exe but in vain).
Which process should I attach on?
That's how you can debug qlik sense connector:
1. You should write in Program class in Main function something like MessageBox.Show("Text");
2. When you try to add connector next time from qlik sense you will see this messagebox. Don't close it!
3. Now you could go to Visual studio and find process to attach to.
4. After you attach, press "ok" on messagebox.
