Looking for an Entity Framework (Core) alternative? Try XPO.

While reading through some comments on a discussion forum, I noticed a discussion about EF Core. They were talking about a specific feature that was missing(can’t remember the feature).

My answer was to try NHibernate but I know that the learning curve is quite steep. Another  person on the forum suggested XPO (eXpress Persistent Objects), a free(!) ORM from DevExpress.

From the site:

eXpress Persistent Objects (XPO) is an Object-Relational Mapping (ORM) tool that handles all aspects of database creation and object persistence, allowing you to concentrate on your application's business logic rather than database complexities. It offers Code First, Model First and Database First development workflows.

Getting started

  • Install the DevExpress XPO nuget package:
dotnet add package DevExpress.Xpo
  • Create a new class that inherits from XPLiteObject or XPObject:
  • Configure the XPO data layer:
  • Create a unit of work and execute a query:

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...

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...
