How to use EF Core pluralizer in runtime scaffold

Tried to use runtime scaffold in EF Core with NpgSql EF Provider

Created scaffolder as described in https://github.com/jdtcn/RuntimeEfCore :

    using Microsoft.CodeAnalysis;
    using Microsoft.CodeAnalysis.CSharp;
    using Microsoft.EntityFrameworkCore;
    using Microsoft.EntityFrameworkCore.Design;
    using Microsoft.EntityFrameworkCore.Diagnostics;
    using Microsoft.EntityFrameworkCore.Scaffolding;
    using Microsoft.EntityFrameworkCore.Scaffolding.Internal;
    using Microsoft.EntityFrameworkCore.Storage;
    using Microsoft.Extensions.DependencyInjection;
    using Npgsql.EntityFrameworkCore.PostgreSQL.Diagnostics.Internal;
    using Npgsql.EntityFrameworkCore.PostgreSQL.Scaffolding.Internal;
    using Npgsql.EntityFrameworkCore.PostgreSQL.Storage.Internal;
    using Humanizer;
    ...
     static IReverseEngineerScaffolder CreatePostgreScaffolder()
      {
      return new ServiceCollection()
        .AddEntityFrameworkNpgsql()
        .AddLogging()
        .AddEntityFrameworkDesignTimeServices()
        .AddSingleton<LoggingDefinitions, NpgsqlLoggingDefinitions>()
        .AddSingleton<IRelationalTypeMappingSource, NpgsqlTypeMappingSource>()
        .AddSingleton<IAnnotationCodeGenerator, AnnotationCodeGenerator>()
        .AddSingleton<IDatabaseModelFactory, NpgsqlDatabaseModelFactory>()
        .AddSingleton<IProviderConfigurationCodeGenerator, NpgsqlCodeGenerator>()
        .AddSingleton<IScaffoldingModelFactory, RelationalScaffoldingModelFactory>()
        // Type or namespace Bricelam not found
        // .AddSingleton<IPluralizer, Bricelam.EntityFrameworkCore.Design.Pluralizer>()
       .AddSingleton<IPluralizer, Humanizer.Pluralizer>()
       .BuildServiceProvider()
       .GetRequiredService();
       }

This causes two compile errors:

> CS0234	The type or namespace name 'Pluralizer' does not exist in the> namespace 'Humanizer' (are you missing an assembly reference?)> > CS0411	The type arguments for method> 'ServiceProviderServiceExtensions.GetRequiredService<T>(IServiceProvider)'> cannot be inferred from the usage. Try specifying the type arguments> explicitly.

.NET 5 EF Core uses Humanizer for pluralization so it should exist.

How to scaffold in runtime from MVC Core application ?
