.NET 6–How to use arguments in your Console app?

In .NET 6 (and newer) when you create a new Console application, the result is really minimal:

That is a big difference if you compare this with what you had before:

This is possible thanks to some new C# features like Top Level Statements and Implicit Using Directives.

But what if you want to use arguments inside your Console app?

Before the arguments where available through the ‘args’ parameter that was available as an argument of the ‘Main’ method. But now there is no method, so what should you do?

Turns out that you can just use the args parameter although it isn’t defined anywhere:

Behind the scenes the compiler will generate a Main method for your and provide the args parameter.

From the documentation:

The entry point method always has one formal parameter, string[] args. The execution environment creates and passes a string[] argument containing the command-line arguments that were specified when the application was started. The string[] argument is never null, but it may have a length of zero if no command-line arguments were specified. The ‘args’ parameter is in scope within top-level statements and is not in scope outside of them. Regular name conflict/shadowing rules apply.

.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...
