Net Core Scaffold-DBContext CustomCandidateNamingService doesn't work in version 2.0.0-preview1

Question

I am using Scaffold-DBContext commnand in order to create a model from my database. I implemented

public class CustomCandidateNamingService : CandidateNamingService
{
    public override string GenerateCandidateIdentifier(string original)
    {
        return original.ToUpper();
    }
}

because I want to return the property name all uppercase. This works in version 1.1.2 but doesn't work in version 2.0.0-preview1-final.

Do I have to change something?

Thanks.

Let's check this repository. https://github.com/arichika/EFCore2.0-Scaffold-DBContext-CustomCandidateNamingService

You need to change the code.

First, It is necessary to create a new class that inherits IDesignTimeServices.
e.g.

public class MyScaffoldingDesignTimeServices: IDesignTimeServices
    {
        public void ConfigureDesignTimeServices(IServiceCollection services)
        {
            services.AddSingleton<ICandidateNamingService,
                                   MyScaffoldingCandidateNamingService>();
        }
    }

Second, Do this.
e.g.

public class MyScaffoldingCandidateNamingService : CandidateNamingService
{
    public override string GenerateCandidateIdentifier(string original)
    {
        return original.ToUpper();
    }
}
