Simplify Source Generator creation the RoslynGenerator template

I’m currently writing my own Source generator which can become quite challenge. Yesterday I talked about RoslynQuoter as one of the tools that helped me along the way. Today I want to show you an easy way to get started thanks to the F0.Templates project.

Start by installing the F0.templates using dotnet new --install F0.Templates:

Now create a new project using the installed RoslynGenerator template dotnet new roslyngenerator.

This will create not only a SourceGenerator project but also a unit and integration tests project and a benchmark project:

Inside the projects we find a simple example of an incremental source generator that searches for methods with the [HelloWorld] attribute and generates an implementation:

Remark: If you are looking for a list of existing generators, take a look here: amis92/csharp-source-generators: A list of C# Source Generators (not necessarily awesome) and associated resources: articles, talks, demos. (github.com)

.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...
