c# - 有谁知道 EF Core 3.0 中的 IPluralizer、ICandidateNamingService 和 CandidateNamingService 发生了什么？

Question

我刚刚更新到 Entity Framework Core 3.0，以下代码不再编译。看起来像 IPluralizer、ICandidateNamingService 和 CandidateNamingService 不再存在。

有谁知道通过 Add-Migration InitialCreate 自定义实体生成的新推荐方法是什么？

public class CustomDesignTimeServices : IDesignTimeServices
{
    public void ConfigureDesignTimeServices(IServiceCollection services)
    {
        services.AddSingleton<ICandidateNamingService, CustomCandidateNamingService>();
       services.AddSingleton<IPluralizer, CustomPluralizer>();
    }
}

public class CustomPluralizer : IPluralizer
{
    public string Pluralize(string name)
    {
        return Inflector.Inflector.Pluralize(name) ?? name;
    }
    public string Singularize(string name)
    {
        return Inflector.Inflector.Singularize(name) ?? name;
    }
}

public class CustomCandidateNamingService : CandidateNamingService
{
    public override string GetDependentEndCandidateNavigationPropertyName(IForeignKey foreignKey)
    {
        if (foreignKey.PrincipalKey.IsPrimaryKey())
            return foreignKey.PrincipalEntityType.ShortName();

        return base.GetDependentEndCandidateNavigationPropertyName(foreignKey);
    }
}

我让 IPluralizer 引用在 .NET 6 中再次工作

<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.9">
  <PrivateAssets>all</PrivateAssets>
  <!-- Remove IncludeAssets to allow compiling against the assembly -->
  <!--<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>-->
</PackageReference>
