ProcessStartInfo hanging on “WaitForExit”? Why?

Question

I have the following code:

info = new System.Diagnostics.ProcessStartInfo(\"TheProgram.exe\", String.Join(\" \", args));
info.CreateNoWindow = true;
info.Win

I solved it this way:

            Process proc = new Process();
            proc.StartInfo.FileName = batchFile;
            proc.StartInfo.UseShellExecute = false;
            proc.StartInfo.CreateNoWindow = true;
            proc.StartInfo.RedirectStandardError = true;
            proc.StartInfo.RedirectStandardInput = true;
            proc.StartInfo.RedirectStandardOutput = true;
            proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;      
            proc.Start();
            StreamWriter streamWriter = proc.StandardInput;
            StreamReader outputReader = proc.StandardOutput;
            StreamReader errorReader = proc.StandardError;
            while (!outputReader.EndOfStream)
            {
                string text = outputReader.ReadLine();                    
                streamWriter.WriteLine(text);
            }

            while (!errorReader.EndOfStream)
            {                   
                string text = errorReader.ReadLine();
                streamWriter.WriteLine(text);
            }

            streamWriter.Close();
            proc.WaitForExit();

I redirected both input, output and error and handled reading from output and error streams. This solution works for SDK 7- 8.1, both for Windows 7 and Windows 8
