I get an AppVeyor error when running unit tests with DNX.

Exception: Error communicating AppVeyor Build Worker API: Could not load file or assembly 'System.Net.Requests, Version=3.9.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

   Also, the same commit built previously in the day:

   That's weird as nothing has been changed recently on AppVeyor build workers. Could it be some external dependency?

   It consistently works on my local computer and consistently (at least now) fails on AppVeyor.

   And there is the message "Error communicating AppVeyor Build Worker API" which is why I guessed it was an AppVeyor thing.

   Right, the exception comes from here: https://github.com/xunit/xunit/blob/4089905f0e7ba13160f6048b32b3a39... and the second part Could not load file or assembly 'System.Net.Requests, Version=3.9.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. could mean that something wrong with the runner itself. I'd recommend filing an issue there: https://github.com/xunit/xunit/issues

   Your test project constantly pulls the latest version of xunit DNX runner: https://github.com/JamesNK/Newtonsoft.Json/blob/master/Src/Newtonso...

   ...and there is a difference between success and failed builds:

   Installing xunit.runner.dnx.2.1.0-beta5-build156 - successful build Installing xunit.runner.dnx.2.1.0-beta5-build159 - failed build

   Hope that helps.
