Client libraries
The libs folder no longer exists in templates after v5.2. That change greatly reduced the size of templates and brought some other advantages.
You can use abp install-libs command for installing or updating client libraries. You should run this command after updating v5.2.
If you're creating a new project, you don't have to be concerned about it, ABP CLI installs client libraries after automatically.
