Xamarin Workbooks

I started experimenting with Xamarin Workbooks as a new(better) way to create my API documentation. Workbooks are an interactive combination of executable code snippets and markdown documentation.

Xamarin Workbooks is a cross platform tool both available for Windows and Mac. Download information is available here: https://developer.xamarin.com/guides/cross-platform/workbooks/install/

After installation, it is time to create your first workbook:

  • Open Xamarin Workbooks. The new C# workbook window is shown. You can choose between a Console iOS, Android or WPF app(at the moment of writing).
    • Xamarin Workbooks uses the concept of agents. Agents are responsible to inject and execute your code in a specific application type. This means there is a seperate agent for WPF, iOS, Android,…
  • Let’s start simple and choose Console.

  • You are welcomed by a blank workbook.

  • In the workbook you can add two types of cells, either an executable C# cell or a documentation cell. Click on the + or “ button to add a new cell.

  • In a C# cell you can enter your C# code. The workbook will provide code completion, syntax coloring, inline live-diagnostics, and multi-line statement support to optimize the editing experience.

  • To execute the code you can hit <enter>, click on the play button or press <control>+<return>.

  • In a Documentation cell you can enter any documentation including images. Formatting is done using the MarkDown format

Some annoyances I have at the moment:

  • I noticed that the editing experience isn’t bug free yet. I got some strange behavior.
  • I couldn’t find a way to include my own assemblies or use my own NuGet server.
  • Compilation is (too) slow.
  • No undo functionality(yet).

It will be interesting to see how this application evolves…

.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...
