I am trying to launch a .NET 8 console application from a .NET 4.8 application and capture the stdout to use that output in the .NET 4.8 application. This all works.

However, if .NET 8.0 is not installed when I launch the console application from a cmd prompt I get the following:

App: C:UsersgtownsendDesktopDistHSInstallPublisherHSInstallPublisher.exe
Architecture: x64
Framework: ‘Microsoft.NETCore.App’, version ‘8.0.0’ (x64)
.NET location: C:Program Filesdotnet

The following frameworks were found:

However, this text does not show up in stdout or stderror when calling the process nor does it throw an exception, it simply closes.

Following is a sample application:

using System;
using System.Diagnostics;
using System.Text;

internal class Program
{
    static void Main(string[] args)
    {
        StringBuilder sb = new StringBuilder();
        var process = new Process();
        process.StartInfo.FileName = @"d:tempDotNet8ConsoleApp.exe";
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.RedirectStandardError = true;
        process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        process.StartInfo.CreateNoWindow = true;
        process.StartInfo.UseShellExecute = false; // Required for redirection
        process.OutputDataReceived += (sender, e) => sb.Append(e.Data);
        process.ErrorDataReceived += (sender, e) => sb.Append(e.Data);
        process.Start();
        process.BeginOutputReadLine();
        process.WaitForExit();
        Console.WriteLine(sb.ToString());
        Console.ReadLine();
    }
}

The output of the above program outputs a blank line.
Any ideas?
