ASP.NET Core Docker error: An assembly specified in the application dependencies manifest (MyApp.deps.json) was not found

Yesterday I had some trouble to get my docker build up and running. However after I succeeded and tried to run my container using docker-compose up, I got the following error message in the container log:

An assembly specified in the application dependencies manifest (MyApp.deps.json) was not found:

    package: 'Microsoft.AspNetCore.Antiforgery', version: '2.0.1'

    path: 'lib/netstandard2.0/Microsoft.AspNetCore.Antiforgery.dll'

  This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:

aspnetcore-store-2.0.3.xml

The problem is caused by the fact that the ASP.NET Core SDK version on the build image(2.0.0) and the referenced version in my project(2.0.3) didn’t match. Easiest solution I could find was resetting the package reference to 2.0.0 in my csproj file:

<Project Sdk="Microsoft.NET.Sdk.Web">

<PropertyGroup>

    <TargetFramework>netcoreapp2.0</TargetFramework>

    <DockerComposeProjectPath>..\docker-compose.dcproj</DockerComposeProjectPath>

  </PropertyGroup>

  <ItemGroup>

    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />

  </ItemGroup>

  <ItemGroup>

    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.2" />

</ItemGroup>

</Project>

After doing that I had to stop and delete the previously created container and build and run a new instance using docker-compose build and docker-compose up.

.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...
