Visual Studio 2022 17.12- Show inline return values while debugging

With the 17.12 version of Visual Studio 2022 there comes a feature that I was waiting to be added for a long time(and with long I really mean long). Of course you are wondering what feature I'm talking about.

Let me first set the scene by showing you the class I want to debug:

I created a small Calculator example. Notice that I'm using 2 different syntaxes(the regular syntax and expression-bodied method). This is not an accidental inconsistency from my side as you’ll see later.

Now what if I wanted to debug the return values of these functions. Before the latest Visual Studio update I typically used a temporary variable to inspect the return values or took a look at the Autos window or the Watch window.

With this release, you finally see the return statements inline in the editor window.

Here is an example where I added the breakpoint at the end of the function:

Unfortunately this doesn’t work (yet?) when using the expression-bodied method syntax, this is because the breakpoint is set on the method body before it is executed:

Still this remains a top feature!

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

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...
