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&lt;TStack&gt;();`
• `PulumiFn.Create(delegate);`
It is the same functionality as before Automation API where you would either:
• `Deployment.RunAsync&lt;TStack&gt;();`
• `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

<https://github.com/pulumi/pulumi/blob/f68b58383142f853bb8d7ff871fd48a4dfa95734/sdk/dotnet/Pulumi/Stack.cs#L66|Here> you can see that `Pulumi.Stack` has an internal constructor that takes in a delegate.

And <https://github.com/pulumi/pulumi/blob/f68b58383142f853bb8d7ff871fd48a4dfa95734/sdk/dotnet/Pulumi/Deployment/Deployment.Runner.cs#L63|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:
```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
