How to collect ReSharper log file

You need to launch Visual Studio with the following parameters:

/ReSharper.LogFile C:\log\resharper_log.txt /ReSharper.LogLevel {Level}

There are a couple of "LogLevel" levels available:

- Verbose

- Trace 

In most of the cases "Verbose" level is enough, so please use it as a default level besides cases when one explicitly asked you to collect logs with the "Trace" level. 

Also the following article can be useful: How to collect ReSharper log file with a specific trace scenario?

All methods of collecting log files are described here: How to collect ReSharper log file?

Hint:

e.g.

to run Visual Studio 2019 via a cmd.exe:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\devenv.exe" /ReSharper.LogFile C:\log\resharper_log.txt /ReSharper.LogLevel Verbose

to run Visual Studio 2015 via a cmd.exe:

"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe" /ReSharper.LogFile C:\log\resharper_log.txt /ReSharper.LogLevel Verbose
