    .AsNoTracking()
    .ToList();

How to create an Entity Framework edmx file for an existing database with .NET Standard and Entity Framework Core?

fixed the issue. Will look into that further Per Microsoft:
"EF Core does not support the EDMX file format for models. The best option to port these models, is to generate a new code-based model from the database for your application."

Port existing code first models, and fluent aPI configuration from Entity Framework 6 to Entity Framework Core 2.0

around this issue
In EF Core 2.0 the Car model changes because of the need to specify the CarOwner foreign key in the Model as a nullable integer property
code :
public class CarConfiguration : IEntityTypeConfiguration<Car>
{
    public void Configure(EntityTypeBuilder<Car> builder)
    {
        builder.HasKey(a => a.Id);
        builder.Property(a => a.Id).ValueGeneratedOnAdd().IsRequired();
        builder.HasOne(x => x.CarOwner)
            .WithMany(x => x.Cars)
            .HasForeignKey("CarOwner_Id") // <--
            .IsRequired(false);
    }
}

public class CarOwnerConfiguration : IEntityTypeConfiguration<CarOwner>
{
    public void Configure(EntityTypeBuilder<CarOwner> builder)
    {
        builder.HasKey(a => a.Id);
        builder.Property(a => a.Id).ValueGeneratedOnAdd().IsRequired();
    }
}
modelBuilder.Entity<Car>()
    .HasOne(x => x.CarOwner)
    .WithMany(x => x.Cars)
    .HasForeignKey("CarOwner_Id");

may help you . I'm trying to build an aspnetcore application over an existing system where the database is already created, and I'm going to add some tables over it. ,
Is there a proper way to handle this scenario?

Can I develop an Asp.net core MVC application using Entity Framework 6 (not Entity Framework core)?
