Is the Stack type still used if an InlineProgram is created? Looking at the code it doesn't seem to be. Does the InlineProgram become the roots stack?

You can still use the stack type. The functionality is on the
PulumiFn
class. It is just another way of providing your pulumi program delegate. You could either: •
PulumiFn.Create<TStack>();
PulumiFn.Create(delegate);
It is the same functionality as before Automation API where you would either: •
Deployment.RunAsync<TStack>();
Deployment.RunAsync(delegate);

Thanks, yeah, I dug through the code. So, with an InlineProgram, when a resource is created the parent isn't auto-set like with a stack, which makes sense.

no that isn't exactly true, there is always a root stack resource. If you aren't using a
TStack
type than internally Pulumi is just doing that for you. I can link you the code 1 sec
Here you can see that
Pulumi.Stack
has an internal constructor that takes in a delegate. And here you can see that if you provide a delegate instead of a
TStack
type than it is just using that internal constructor, so there is always a root
Pulumi.Stack
resource.

In both cases,
TStack
and delegate programs, the following code:
Copy code
var parent = type == Stack._rootPulumiStackTypeName
                ? null
                : (options.Parent ?? Deployment.InternalInstance.Stack);
parent
would be set by
Deployment.InternalInstance.Stack
It just ensures that
Pulumi.Stack
resource never has a parent
