Operation could destabilize the runtime

This Friday, I had the most scariest exception ever:

"System.Security.VerificationException: Operation could destabilize the runtime.”

Sounds like all hell could break loose. How did I got this exception?

I was trying the Entity Framework integration for IBM DB2 and I was trying to load an entity which had a timestamp column in the database. The issue was caused by the Entity Framework query translator which couldn’t understand how to map this database type could be mapped to a datetime in code.

A more meaningful exception message would have been nice. It took me a lot of time to figure out the reason for this error.

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...
