MassTransit–.NET 8 upgrade errors - No service for type 'MassTransit.Saga.ISagaRepositoryContextFactory`1[MassTransit.JobTypeSaga]' has been registered.

While upgrading an application to .NET 8 (and upgrading to the latest MassTransit version along the way), I stumbled over some Masstransit specific issues after the upgrade.

The first error I got after upgrading my application to .NET 8 was the following:

No service for type 'MassTransit.Saga.ISagaRepositoryContextFactory`1[MassTransit.JobTypeSaga]' has been registered.

This error is related to the Job Consumers feature. Job consumers internally use sagas to manage the job state, retries, etc…

I got the application back up and running by explicitly registering a saga repository provider like this:

Of course if you want your saga’s to survive an application restart, it is better to use a persistent saga repository like Entity Framework:

That fixed the application errors I got, tomorrow we have a look at the warnings...

.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...
