Running PowerShell from MSdeploy runcommand does not exit
Your scenario and problem look similar to this reported issue:PowerShell.exe can hang if STDIN is redirected
If this is the case then try this workaround: use -inputformat none:
powershell.exe -inputformat none C:\temp\WebDeploy\Package\HelloWorld.ps1I have tried this with "a fake msdeploy" program that calls the .bat file like this:
using System.Diagnostics;class Program{ static void Main(string[] args) { ProcessStartInfo si = new ProcessStartInfo(); si.FileName = "cmd.exe"; si.Arguments = "/c " + args[0]; si.RedirectStandardInput = true; si.UseShellExecute = false; var process = Process.Start(si); process.WaitForExit(); }}This demo does have the same problem that you describe and the workaround helps. If msdeploy calls the .bat file in the same or similar way then hopefully this is a solution.
powershell.exe -file ScriptFile.ps < CONThis solve the problem without resorting to undocumented features.
