In PowerShell repository we have to use pinvoke to support WindowStyle without UseShellExecute.

Today .Net supports WindowStyle only if UseShellExecute is true

runtime/src/libraries/System.Diagnostics.Process/src/System/Diagnostics/Process.Win32.cs

Lines 23 to 30 in 58719ec

private bool StartCore(ProcessStartInfo startInfo)
{
return startInfo.UseShellExecute
? StartWithShellExecuteEx(startInfo)
: StartWithCreateProcess(startInfo);
}
private unsafe bool StartWithShellExecuteEx(ProcessStartInfo startInfo)

Current request is to add support for WindowStyle (on Windows) if UseShellExecute is false

runtime/src/libraries/System.Diagnostics.Process/src/System/Diagnostics/Process.Windows.cs

Line 427 in 58719ec

private unsafe bool StartWithCreateProcess(ProcessStartInfo startInfo)

It looks like a very simple implementation.
We would like confirmation soon from the .Net team that this can be implemented in .Net 8 so that we can avoid unnecessary work in the PowerShell repository.
