DotCover won't do coverage


Trying to run coverage on my unit tests and it keeps failing


2018.07.27 12:49:58.742 ERROR Coverage analysis: Processing coverage snapshots: 'C:\Users\USERNAME\AppData\Local\Temp\ssd.Sapywip.tmp' failed: The given key was not present in the dictionary.


The coverage window is empty as well. I've tried clearing cache and all that. This just happened after both updating VS2017 pro and Resharper.


Hi Aaron,

Could you please do the following actions:

  • close your solution
  • go to %temp%\JetBrains\ReSharperPlatformVs[N]\vAny_[XXX]\CoverageData folder
  • find _[YourSolutionWithBrokenCoverage].[XXX] folder and remove it. It would also be great if you could send this folder to us for an investigation. If the folder is too big for sending, you could upload it to our FTP or share it via any cloud services like Dropbox.
  • reopen the solution and repeat coverage analysis

It should solve the problem.
