I solve the problem, putting this on csproj

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
   <PreserveCompilationContext>true</PreserveCompilationContext>
   <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish>
  </PropertyGroup>

The key is the “MvcRazorExcludeRefAssembliesFromPublish” tag

The main problem in using Library for storing the Embedded Views. Here is an explanation: https://github.com/aspnet/Mvc/issues/6021

So I had to clean up the library csproj file from any additional configuration and add <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish> to the WebApp itself.
