DeleteNamespacedAsync hangs indefinitely

[justinmchase]

Describe the bug
I am awaiting await generic.DeleteNamespacedAsync<T>(...) but it never returns.

Kubernetes C# SDK Client Version
16.0.7

Server Kubernetes Version
1.30.5

Dotnet Runtime Version
net8

To Reproduce

1. Follow the CRD example app
2. Create an instance of the CR in a namespace
3. Delete it from the namespace

await generic.DeleteNamespacedAsync<CResource>(
  this.Namespace,
  tunnel.Metadata.Name,
  cancellationToken
);

Expected behavior

1. The resource id deleted from kubernetes
2. This method returns immediately after

KubeConfig
N/A

Where do you run your app with Kubernetes SDK (please complete the following information):

• OS: Linux
• Environment: container
• Cloud: Docker Desktop

Additional context

I have a watcher going at the same time:

await foreach (var (eventType, resource) in generic.WatchNamespacedAsync<T>(this.Namespace, cancel: cancellationToken))

This is detecting the resource being deleted and it keeps operating fine without hanging, I can manually create and delete more resources in kube and this watcher responds as normal. I'm also calling a PatchNamespacedAsync<T> and that one returns fine, its specifically deletion thats appears to hang.

i believe this is not an SDK issue

kubectl will stuck as well when your finalizer of ns blocked you from deleting it.
you can kubectl patch namespace yourns -p '{"metadata":{"finalizers":[]}}' --type=merge
