How to ingration test Console App attached to Visual Studio debugger

I'm making a Console App and I want to create the kind of integration/component tests I'm used to for ASP.NET Core applications using WebApplicationFactory<>.

However, I haven't been able to find a way to test the Console App in an attached way that ensures I can set breakpoints in the Console App during debugging tests.

I have tried to hack something together using the following answer, but I didn't achieve breakpoints. By the time it's trying to attach, the process has already terminated.

Is there a better way I'm overlooking?

Simplified version of my current code:

internal class Program { static async Task Main(string[] args) { var host = Host.CreateDefaultBuilder(args) .UseConsoleLifetime() .ConfigureServices((_, services) => services.AddHostedService<CustomHostedService>()) .Build(); await host.RunAsync(); } } 

internal class CustomHostedService : IHostedService { private readonly IHostApplicationLifetime _hostApplicationLifetime; public CustomHostedService(IHostApplicationLifetime hostApplicationLifetime) { _hostApplicationLifetime = hostApplicationLifetime; } public async Task StartAsync(CancellationToken cancellationToken) { // Actual code for the application _hostApplicationLifetime.StopApplication(); } public Task StopAsync(CancellationToken cancellationToken) => Task.CompletedTask; } 

internal class IntegrationTests { [Fact] public void Executable() { Process.Start("{assemblyName}.exe {arguments}") // Asserts } [Fact] public void DotnetRun() { Process.Start("dotnet", "run --project {project_path} {arguments}"); // Asserts } }
