Check compatibility between .NET versions

Compatibility is a very important goal of the .NET team at Microsoft. The team always made a great deal to guarantee that newer versions will not break previous functionality. However sometimes this is unavoidable to address security issues, fix bugs or improve performance.

To understand the consequences you have to make a difference between runtime changes and retargeting changes:

  • Runtime changes: Changes that occur when a new runtime is placed on a machine and the same binaries are run, but expose different behavior
  • Retargeting changes: Changes that occur when an assembly that was targeting .NET FW version x is now set to target version y. 

To help you identify possible compatibility issues, Microsoft created the .NET Compatibility Diagnostics, a set of Roslyn based analyzers.

Here is how to use them:

  • First you have to choose if you want to check for Runtime changes or for Retargeting changes
  • Now you need to select the ‘From .NET Framework version’ and the ‘To .NET Framework version’:

  • After making your selection, you’ll get a list of all changes classified by their impact:

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         ...
