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:


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">






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



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



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.
