Error running tests in Visual Studio 2017: No process is on the other end of the pipe

Question

Sometimes when I run my tests (.Net Standard 2.0 project using XUnit) I get an error in the Tests output pane saying:

[25.09.2018 1:46:36 Error] System.IO.IOException: No process is on the other end of the pipe."

And then I can't run the tests any more until I restart the Visual Studio. Here's the full stacktrace for the error:

 at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.Console.GetBufferInfo(Boolean throwOnNoConsole, Boolean& succeeded)
   at System.Console.get_ForegroundColor()
   at Microsoft.VisualStudio.TestPlatform.Utilities.OutputExtensions.SetColorForAction(ConsoleColor foregroundColor, Action action)
   at Microsoft.VisualStudio.TestPlatform.Utilities.OutputExtensions.Warning(IOutput output, Boolean appendPrefix, String format, Object[] args)
   at Microsoft.VisualStudio.TestPlatform.CommandLine.Internal.ConsoleLogger.RaiseTestRunWarning(String warningMessage)
   at Microsoft.VisualStudio.TestPlatform.CommandLine.TestPlatformHelpers.TestRequestManager.UpdateRunSettingsIfRequired(String runsettingsXml, List`1 sources, String& updatedRunSettingsXml)
   at Microsoft.VisualStudio.TestPlatform.CommandLine.TestPlatformHelpers.TestRequestManager.RunTests(TestRunRequestPayload testRunRequestPayload, ITestHostLauncher testHostLauncher, ITestRunEventsRegistrar testRunEventsRegistrar, ProtocolConfig protocolConfig)
   at Microsoft.VisualStudio.TestPlatform.Client.DesignMode.DesignModeClient.<>c__DisplayClass19_0.<StartTestRun>b__0()

Is there anything I can do to get rid of this annoying behavior?

Answer 1

Just update your Visual Studio 2017 to the latest version and this nasty bug is gone.

Answer 2

for me just restarting VS 2017 helped be get rid of this error, exact same error.
