PowerShell hangs when exiting having used a PowerShell runspace pool/runspace #5205
Description
PowerShell Core hangs when exiting and using a PowerShell runspace pool. On Windows PowerShell it exits successfully.
Steps to reproduce
here's the gist for my code: https://gist.github.com/tylerl0706/2d87a13c6147278bb4e8565585aa9722
Steps:
PS > Add-Type -Path "path/to/TestHttpListener/bin/Debug/netstandard2.0/TestHttpListener.dll"
PS > $app = [TestHttpListener.TestHttpListener]::new()
PS > $app.Start(8081)
PS > Invoke-WebRequest -Uri http://localhost:8081 # VERY IMPORTANT
PS > exitExpected behavior
PowerShell successfully exists
Actual behavior
PowerShell hangs and doesn't give the prompt back - this is causing my AppVeyor and Travis builds to fail due to timeout :(
