  * Starting from `2.0`, [dotnet sdk versioning](https://github.com/kubernetes-client/csharp/issues/400) adopted
  * `Kubernetes Version` here means the version sdk models and apis were generated from
  * Kubernetes api server guarantees the compatibility with `n-2` version. for exmaple, 1.19 based sdk should work with 1.21 cluster, but no guarantee works with 1.22 cluster. see also <https://kubernetes.io/releases/version-skew-policy/>
+ * `*` `KubernetesClient.Classic`: netstandard2.0 and net48 are supported with limited features
