Why cant I start a process without using ShellExecute set to true?

So I'm currently trying to start the Command Prompt window from my ASP.NET Core MVC WebApp which is running in Debug mode when I click a button but for some reason it won't start unless I specify UseShellExecute and set it to True.

This is a problem since if I do set it to True I can't redirect standard input which is a bad thing. I need to be able to do that.

Here is the code

public static void Start(string dirPath)
{
    Process serverProcess = new Process
    {
        StartInfo =
        {
            CreateNoWindow = false,
            FileName = "cmd.exe",
            Arguments = "",
            WindowStyle = ProcessWindowStyle.Maximized,
            RedirectStandardInput = true
        }
    };   

    serverProcess.Start()
}

It does invoke the code, because keep in mind, it works when I do UseShellExecute = True and it also hits the breakpoints etc.

How do I start the cmd or a specific batch file without setting UseShellExecute = True ?

UseShellExecute is false by default for Core . If you don't want to set UseShellExecute . Try setting Arguments below as workaround :

Arguments = $"/c start cmd.exe",
