Use Logs

If you experience any problems with ReSharper, you can also log the execution and pinpoint the problem. The logs could also be helpful to provide details on possible problems to the support team.

Logging in Visual Studio

When working with ReSharper in Visual Studio, you can enable logging by starting Visual Studio devenv.exe with the following command line arguments:

  • /ReSharper.LogFile - The log will be saved in %TEMP%\JetLogs folder with auto-generated name.

  • /ReSharper.LogFile path_to_the_log_file - The log will be saved in the specified location.

By default the main log includes interactions between Visual Studio and ReSharper as well as error messages from ReSharper core subsystems. If necessary, you can use additional argument to switch between different levels of log messages:

/ReSharper.LogLevel [Normal|Verbose|Trace]
  • Most of the core logs are embedded into the main log

  • Some of the core logs are stored as additional lgc*.tmp files in the %TEMP% directory.

  • The workspace host logs are stored in the %TEMP%JetLogs directory.
