  • Steps to reproduce the issue:"
  1. Generate a new microservice solution with: abp new AppMicro -t microservice-pro -u blazor-server

  2. start infrastructure with powershell ./up.ps1

  3. tye run and check logs for Blazor and Public-web. Both contain same error :

    Could not load type 'Volo.Abp.IAsyncInitialize' from assembly 'Volo.Abp.Core, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null'.

Was it removed in 5.3 without updating the microservice template. or where is my mistake ?

    I was able to fix it my own by follwing these steps:

    • i did stop all docker container and removed alle volumes: docker volume prune -f
    • i uninstalled abp-cli and suite
    • i did remvoe the .abp folder from %userprofie%
    • i did remove within the .nuget folder from %userprofile% all Volo Packages
    • i reinstalled abp-cli and suite
    • i generated a new microservice-template like above

    I am not sure what was the right step.. but now it works. please refund that credit
