ASP.NET Core - Load session state asynchronously

While browsing through the ASP.NET Core documentation I noticed the following section: Load session state asynchronously.

The default session provider in ASP.NET Core loads session records from the underlying IDistributedCache backing store asynchronously only if the ISession.LoadAsync method is explicitly called before the TryGetValue, Set, or Remove methods. If LoadAsync isn't called first, the underlying session record is loaded synchronously, which can incur a performance penalty at scale.

To have apps enforce this pattern, wrap the DistributedSessionStore and DistributedSession implementations with versions that throw an exception if the LoadAsync method isn't called before TryGetValue, Set, or Remove. Register the wrapped versions in the services container.

To avoid this performance penalty, I created 2 extensions methods that do a LoadAsync before reading or writing the session state:

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
