MassTransit–.NET 8 upgrade warnings

After upgrading to MassTransit 8.1, I got a list of warnings. In this post I'll walk you through the list of warnings and how I fixed them. Let's get started...

ConsumerDefinition warning

The first warning I got was the following:

'ConsumerDefinition<T>.ConfigureConsumer(IReceiveEndpointConfigurator, IConsumerConfigurator<T>)' is obsolete: 'Use the IRegistrationContext overload instead. Visit https://masstransit.io/obsolete for details.'

That is an easy one to fix, I had to rewrite my original ConsumerDefinition:

To a version that uses the IRegistrationContext as one of the parameters:

InMemory Outbox warning

A second warning was related to the usage of the InMemoryOutbox:

'InMemoryOutboxConfigurationExtensions.UseInMemoryOutbox(IConsumePipeConfigurator, Action<IOutboxConfigurator>)' is obsolete: 'Use the IRegistrationContext overload instead. Visit https://masstransit.io/obsolete for details.'

Here is the original consumerdefinition that caused the warning:

And here is the updated code:

Job Consumers warning

A last warning was related to the Job consumers configuration:

'RegistrationContextExtensions.ConfigureEndpoints<T>(IServiceInstanceConfigurator<T>, IBusRegistrationContext, IEndpointNameFormatter)' is obsolete: 'Job Consumers no longer require a service instance. Visit https://masstransit.io/obsolete for details.'

My original configuration looked like this:

Now I can remove the ConfigureJobServiceEndpoints line:

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...
