efcore: The current CSharpHelper cannot scaffold literals of type 'Microsoft.EntityFrameworkCore.Metadata.Internal.DirectConstructorBinding'. Configure your services to use one that can.

I’s using dotnet core 2 and EF core 2. I use CLI to generate migration files. In module which i try to generate Migration file, i use this factory:

`
public class ApplicationDbContextFactory : IDesignTimeDbContextFactory<ChakavakIdentityDbContext> {

    public ChakavakIdentityDbContext CreateDbContext(string[] args)
    {
        var builder = new DbContextOptionsBuilder();
        //Database Migrations must use a relational provider. Microsoft.EntityFrameworkCore.InMemory is not a Relational provider and therefore cannot be use with Migrations.
        //builder.UseInMemoryDatabase("EmployeeDB");
        //You can point to use SQLExpress on your local machine
        var connectionstring = "Server=.;Database=Chakavak1; Trusted_Connection=True;MultipleActiveResultSets=true";
        builder.UseSqlServer(connectionstring);
        
        return new ChakavakIdentityDbContext(builder.Options);
    }
}

` And here is project file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <RuntimeFrameworkVersion>2.0.0</RuntimeFrameworkVersion>

But when i run dotnet ef migrations add initial --verbose, i run into this message
