NuGet Restore error - Response status code does not indicate success: 401 (Unauthorized)

When trying to build a project in Visual Studio, it failed while downloading the nuget packages from our internal Azure Artifacts nuget store.

In the logs I could find the following error message:

C:\Program Files\dotnet\sdk\3.0.100\NuGet.targets(123,5): error : Failed to retrieve information about 'Example.WebApi.Client' from remote source 'http://tfs:8080/tfs/DefaultCollection/_packaging/892779dc-d854-4c9f-8b26-833d52585ae6/nuget/v3/flat2/example.webapi.client/index.json'. [C:\Projects\MapSU\MapSU.Server.sln]

C:\Program Files\dotnet\sdk\3.0.100\NuGet.targets(123,5): error :   Response status code does not indicate success: 401 (Unauthorized). [C:\Projects\MapSU\MapSU.Server.sln]

Directly accessing the Azure Artifacts url worked without a problem, but when I tried to do this through Visual Studio or through the commandline it failed with the error above.

I was able to solve the problem by removing the ‘vscredentials’ in the Windows Credentials manager that referred to the tfs server:

  • Open the search bar in windows and search for Credentials Manager
  • Click on Manage Windows Credentials.
  • In the Credential Manager go to ‘Windows Credentials’
  • Scroll to the list of Generic Credentials. Click on the vscredentials one and click on Remove.

Now try to access Azure Artifacts again in Visual Studio. This time I got a login popup, after entering the correct credentials everything worked again.

.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...
