If I want to write a CLI application...

[atrauzzi]

Is there any advice that I can follow so that the application can consume everything abstracted by Aspire? Like say I have a database and I want to run some maintenance tasks. Or maybe even use EFs migration bundling...

(etc) 🙂

What do you mean exactly? That you want to write a cli application that uses the aspire components? Or something else?

[atrauzzi]

I think that's the same thing, yeah. So right now I write CLI applications that can perform one-off tasks for me.

I can run them locally, or in prod environments, set these up using Cloud Run Jobs / Azure Container App Jobs to be triggerable.

Of course, if I'm going to run a CLI application on my workstation that's running things through aspire, perhaps I can leverage discovery and configuration?

From what I have seen, Aspire components are built using the IHostApplicationBuilder which is not limited to web apps, but can also be used for console apps. You can read more about how to use it for a console app here.

If you want a short lived appplication, you can do something like this

var builder = Host.CreateApplicationBuilder();

// This is stuff from Aspire
builder.AddServiceDefaults();
builder.AddNpgsqlDbContext<MyDbContext>("Postgres");

using var host = builder.Build();

var dbContext = host.Services.GetRequiredService<MyDbContext>();
// Do stuff here

Or if you want a long lived application, you can implement a hosted service and run the host instead of just building it.

Works for me! Thank you 🙂
