Description Henric Müller 2016-09-20 07:14:20 UTC
Trying to start a process with " " as name generates native error code FILE_NOT_FOUND (2), but running the same in .NET generates NativeErrorCode ERROR_INVALID_PARAMETER (87). Currently running this on Windows gives ACCESS_DENIED (5).

NativeErrorCode should match the one that the .NET runtime gives and should therefore be ERROR_INVALID_PARAMETER (87) on all platforms.

Code to reproduce the issue:

		Process process = new Process ();
		process.StartInfo = new ProcessStartInfo (" ");
		process.StartInfo.UseShellExecute = false;
		try {
			process.Start ();
		} catch (Win32Exception ex) {
			Console.WriteLine("NativeErrorCode (should be 87):" + ex.NativeErrorCode);
