.NET 7 - The StringSyntaxAttribute

With the release of .NET 7, a new attribute was introduced; the StringSyntaxAttribute.

What does the StringSyntaxAttribute do?

The StringSyntaxAttribute allows you to tag strings. It can be applied to fields, properties, and parameters and provides tools like Visual Studio with information about the nature of the string.

The compiler will use this information to provide the correct syntax highlighting:

In this release following string formats can be used out of the box (and it is possible to create custom ones):

  • CompositeFormat: The syntax identifier for strings containing composite formats for string formatting.
  • DateOnlyFormat: The syntax identifier for strings containing date format specifiers.
  • DateTimeFormat: The syntax identifier for strings containing date and time format specifiers.
  • EnumFormat: The syntax identifier for strings containing Enum format specifiers.
  • GuidFormat: The syntax identifier for strings containing Guid format specifiers.
  • Json: The syntax identifier for strings containing JavaScript Object Notation (JSON).
  • NumericFormat: The syntax identifier for strings containing numeric format specifiers.
  • Regex: The syntax identifier for strings containing regular expressions.
  • TimeOnlyFormat: The syntax identifier for strings containing time format specifiers.
  • TimeSpanFormat: The syntax identifier for strings containing TimeSpan format specifiers.
  • Uri: The syntax identifier for strings containing URIs.
  • Xml: The syntax identifier for strings containing XML.

Remark: Not all of the above formats are recognized by Visual Studio at the moment of writing.

.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...
