Hi,

We have the problem that sometimes xUnit won't work well. We have a powershell script, and everything looks fine, but still it reports a failure.

https://ci.appveyor.com/project/Xharze/nlog-134/build/4.0.692

Can you see what's wrong here? We use the `2> out-null`, because (in the recent) past, xUnit was crashed due to logging to the error stream .

   Have you tried executing runners from batch ("CMD" mode)?
   Otherwise, try checking $LastExitCode instead of $?.

   With $LastExitCode we got the same results.
   See; https://ci.appveyor.com/project/Xharze/nlog-134/build/4.0.696

   I'm not sure how to convert to CMD for the test.

   Current code:

           .\tests\CreateTestUsers.cmd

           xunit.console.clr4 "build\bin\Debug\.NET Framework 4.0\NLog.UnitTests.dll" /appveyor /noshadow 2> out-null

           $success = $LastExitCode

           xunit.console.clr4 "build\bin\Debug\.NET Framework 4.5\NLog.UnitTests.dll" /appveyor /noshadow 2> out-null

           if ( $success ) {
             $success = $LastExitCode
           }

           xunit.console.clr4 "build\bin\Debug\.NET Framework 3.5\NLog.UnitTests.dll" /appveyor /noshadow 2> out-null

           if ( $success ) {
             $success = $LastExitCode
           }

           if ( -not $success) {
              throw "tests not successfull"

   Like that: https://github.com/FeodorFitsner/NLog/blob/master/appveyor.yml

   Build results: https://ci.appveyor.com/project/FeodorFitsner/nlog/build/4.0.2

   Thanks!

   It seems to work!

   Is this a "fail fast" solution?
