Maybe try creating the ReleaseArgs object within the namespace apply function? Expand the apply function so that it returns the entire ReleaseArgs object.

Is ReleaseArgs an accurate type? Usually the property type objects are named like IngressControllerHelmOptionsArgs. Maybe the implicit cast to Input&lt;T&gt; isn't working because it trying to do a double cast from ReleaseArgs, try explicitly casting to that property type? I'm not at my computer so can't look at the documentation to examine the types but I can in a bit

the property is declared as `public Input&lt;Inputs.ReleaseArgs&gt;? HelmOptions { get; set; }`

<@U02RN6CC6LB> if you're using an apply, the name will be a string, looks like the component isnt satisfied with a string. Have you tried just:
```appServicesNamespace.Metadata.Name```

(bearing in mind dotnet is not my strong suit)

okay, you might be better implenting directly as a helm release in that case

```        var ingress = new Chart("nginx-ingress", new ChartArgs
        {
            Chart = "ingress-nginx",
            Namespace = "app-services",
            Version = "4.0.13",
            FetchOptions = new ChartFetchArgs
            {
                Repo = "<https://kubernetes.github.io/ingress-nginx>"
            },
            Values = new Dictionary&lt;string, object&gt;
            {
                ["controller"] = new Dictionary&lt;string, object&gt;
                {
                    ["publishService"] = new Dictionary&lt;string, object&gt;
                    {
                        ["enabled"] = true
                    }
                },
            }
        });```

this is I tried with that, and it fails after a bunch of warnings about hooks

try the `helm.Release` rather than `helm.Chart`

Chart doesn't support hooks, `Release` does
