How to get dotCover logs?

Answer

To troubleshoot your issue, the dotCover support team may ask you to provide dotCover log files. The procedure of taking logs differs depending on the way you run dotCover: in Visual Studio, standalone, or using the console runner. By default, log files are saved to the %Temp%\JetLogs folder.

Note, the instructions below include additional steps for dotCover core logs. These steps are only necessary when explicitly requested by our support team for advanced troubleshooting. For most issues, you can skip these log collection procedures.
