How to prevent a process started by Process.Start() from exiting when my app exits?

Question

my method...

private static void RunAndExit(string command)
{
    var processInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        Arguments = "/c " + command,
        CreateNoWindow = false,
        UseShellExecute = true,
        RedirectStandardError = false,
        RedirectStandardOutput = false
     };
    }

I want the process started by RunAndExit() to continue to run after the app containing this method has exited. Thanks for any help!

ops I doubt that you can achieve this due to windows architecture — BRAHIM Kamel, Jun 20 '14 at 14:14
The child process isn't exiting because its parent exited. It may be exiting because its standard input and output streams started producing errors. — Ben Voigt, Jun 20 '14 at 14:28
I realize now that vstest.console is part of the issue. This code is part of a unit test. If I run the unit test through vstest.console.exe (replacement for MSTest) the process will go away when vstest.console exits. If, however, I run this test from Visual Studio test explorer, it will not go away when the test is finished nor when I close Visual Studio. — user3574948, Jun 20 '14 at 16:03
also, I made an error in copying the code over. There is a call to Process.Start(processInfo) in the real code. — user3574948, Jun 20 '14 at 16:04
Well, I guess I answered the question you asked based on the code you provided. — David Heffernan, Jun 20 '14 at 18:28

Your code will already achieve that, so long as you actually start the new process. You are missing a call to Process.Start().

private static void RunAndExit(string command)
{
    var processInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        ....
    };
    Process.Start(processInfo); // add this line
}
