Entity Framework Tooling: GraphDiff

While looking for a good solution to save a detached object tree using Entity Framework, I found the perfect solution:GraphDiff.
GraphDiff offers a set of DbContext extension methods for Entity Framework Code First, that allow you to save an entire detached Model/Entity, with child Entities and Lists, to the database without writing the code to do it. It has the following features to offer:
  • Merge an entire graph of detached entities to the database using DbContext.UpdateGraph();
  • Ensures concurrency is maintained for all child entities in the graph
  • Allows for different configuration mappings to ensure that only changes within the defined graph are persisted
  • Comprehensive testing suite to cover many (un/)common scenarios.
GraphDiff is really easy to use. Just take your object tree and tell Entity Framework how to attach the child objects:

This is a must have for every Entity Framework user!

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...
