Capturing output from CMD in a WPF window

I'm currently trying to have a simple CMD function run from my C# WPF program, and display the output in the WPF program. I think I'm close, but its not currently displaying anything. The program will open and have a confirmation that it should run the CMD file. Once 'Yes' is selected, it should open a new frame and run the program, piping it back to the frame. The CMD referenced is a simple netstat cmd. I have changed 'CreateNoWindow' to False and see the CMD opening, so it seems to be executing it.

EDIT: I left out a section of my code, whoops!

EDIT 2: Updated code to include some suggestions. No change. Could it be something to do with how I'm using a Frame?

namespace WpfApp1
{
/// <summary>
/// Interaction logic for Page3.xaml
/// </summary>
    public partial class Page3 : Page
    {
        public Page3()
        {
            InitializeComponent();
        }

        private void Frame_Navigated(object sender, NavigationEventArgs e)
        {
            Task.Run(() => { Muntrainout(); });
        }

        public void Muntrainout()
        {
            System.Diagnostics.Process muntrainout = new System.Diagnostics.Process();
            muntrainout.StartInfo.RedirectStandardOutput = true;
            muntrainout.StartInfo.RedirectStandardError = true;
            muntrainout.StartInfo.RedirectStandardInput = true;
            muntrainout.StartInfo.UseShellExecute = false;
            muntrainout.StartInfo.CreateNoWindow = true;
            muntrainout.StartInfo.FileName = @"C:\Users\user.name\Documents\Project\Test.cmd"; 
            muntrainout.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler((sender, e) =>
                 {
                     Console.WriteLine(e.Data);
                 }
            );
            // Error Handling
            muntrainout.ErrorDataReceived += new System.Diagnostics.DataReceivedEventHandler((sender, e) => { Console.WriteLine(e.Data); });
            muntrainout.Start();
            muntrainout.BeginOutputReadLine();
            muntrainout.WaitForExit();
        }
    }
}

Assuming you want to display the output in your frame...

this works for me:

muntrainout.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler((sender, e) =>
            {
                //Console.WriteLine(e.Data);
                Frame1.Dispatcher.Invoke(() => { Frame1.Content += e.Data+Environment.NewLine; });

            }

It looks a bit ugly but it displays the output... I don't know how Console.WriteLine() should write to your frame?
