ASP.NET Core API Versioning

A lot has been written about API versioning and the opinions differ on what the 'best' approach is.

I'm not planning to add an extra opinion to the mix, instead I want to focus on one of the ways you can do API versioning in ASP.NET Core.

Versioning by content type

When using versioning by content type, we use custom media types instead of generic types such as application/json. To make this work we can rely on content negotiation inside our API.

Here is an example:

Accept: application/vnd.example.v1+json
Accept: application/vnd.example+json;version=1.0

Inside our ASP.NET Core controllers, we have to introduce the [Consumes] attribute. This attribute allows an action to influence its selection based on an incoming request's content type by applying a type constraint.

What about Minimal API’s?

At the moment of writing, ASP.NET Core Minimal API’s don’t support content negotiation (yet).

I’m really bad at remembering emoji’s. So here is cheat sheet with all emoji’s that can be used in tools that support the github emoji markdown markup: All credits go to rcaviers who created this list.

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

DevToys–A swiss army knife for developers

As a developer there are a lot of small tasks you need to do as part of your coding, debugging and testing activities. DevToys is an offline windows app that tries to help you with these tasks. Instead of using different websites you get a fully offline experience offering help for a large list of tasks. Many tools are available. Here is the current list: Converters JSON <> YAML Timestamp Number Base Cron Parser Encoders / Decoders HTML URL Base64 Text & Image GZip JWT Decoder Formatters JSON SQL XML Generators Hash (MD5, SHA1, SHA256, SHA512) UUID 1 and 4 Lorem Ipsum Checksum Text Escape / Unescape Inspector & Case Converter Regex Tester Text Comparer XML Validator Markdown Preview Graphic Color B
