if (hostProcess.ExitCode != 0) // 1. When process output is read asynchronously, WaitForExit() without a timeout blocks until child processes
// are killed, which can cause hangs due to MSBuild NodeReuse child processes started by dotnet.exe.
// With a timeout, WaitForExit() returns when the parent process is killed and ignores child processes.

//
// 2. If "dotnet publish" does hang indefinitely for some reason, tests should fail fast with an error message.
