Are there any additional details in the ActivityLog.xml?
You mentioned that the details were lost, is there anything there that can be useful?
Perhaps regarding the SLAF extension (which is part of the SonarLint extension)? Or any other āSetSite failed for packageā errors with the stack trace?
Visual Studio overwrites the ActivityLog.xml.
Should have saved that after the issue.
I donāt know why the SL extensions did not uninstall on the first attempt - if a MEX (cache) corruption was the issue, un-installing and re-installing fixed that.
Next time, Iāll save the log files.
Update: this looks to be caused by MEF cache corruption. We canāt do anything to stop the cache corruption, but we could try to improve the user experience when it occurs. Weāve created SLVS-3029 to track this.
