如何在multipleDbContext中配置Ef core 2.0中的一对多外键

Question

我正在尝试在我的项目中实现DDD。 我在每个解决方案中都有不同的解决方案（每个Bounded Context）和dbcontext。 与产品和客户管理的Master.sln以及SalesOrder Management的SalesOrder.sln类似。

问题在于，当我已经为Master迁移并尝试使用Contact和Product在SalesOrder中配置外键时（Contact是RetailContact，Product是SalesOrderDbContext中的RetailProduct）迁移正在为Product和Customer Table生成脚本因为我已经在我的数据库中有产品和客户（通过MasterDbContext更新），所以在更新我的数据库时会发生冲突。忽略产品和客户时，未配置外键。

我正在寻找一种在多个DbContext中配置外键关系的方法，同时忽略不同DbContext中已经创建的表。

MasterDbContext

    public MasterDbContext(DbContextOptions<MasterDbContext> options) : base((DbContextOptions)options)
    {

    }

    public DbSet<Product> Products { get; set; }
    public DbSet<ProductCategory> ProductCategories { get; set; }

    public DbSet<WareHouse> WareHouses { get; set; }
    public DbSet<Contact> Contacts { get; set; }


    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.HasDefaultSchema("Master");
        base.OnModelCreating(modelBuilder);
    }
}

SalesOrder.sln中的SalesOrderDbContent

    public class SalesOrderDbContext : DbContext
{
    public SalesOrderDbContext(DbContextOptions<SalesOrderDbContext> options) : base(options)
    {

    }

    public DbSet<RetailMilkOrder> RetailMilkOrders { get; set; }
    public DbSet<DistributorOrder> DistributorOrders { get; set; }


    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<WareHouse>().ToTable("WareHouses");
        modelBuilder.Entity<RetailContact>().ToTable("Contacts");
        modelBuilder.Entity<RetailProduct>().ToTable("Products");
        modelBuilder.Ignore<RetailProduct>();

        modelBuilder.HasDefaultSchema("SalesOrder");



        modelBuilder.ApplyConfiguration(new RetailMilkOrderConfiguration());
        modelBuilder.ApplyConfiguration(new RetailMilkOrderItemConfiguration());


        base.OnModelCreating(modelBuilder);
    }
}

public class RetailMilkOrderItemConfiguration : IEntityTypeConfiguration<RetailMilkOrderItem>
{
    public void Configure(EntityTypeBuilder<RetailMilkOrderItem> itemConfig)
    {


        itemConfig.ToTable("RetailMilkOrderItems");
            itemConfig.HasOne<RetailProduct>()
            .WithMany()
            .HasForeignKey(itm =>itm.RetailProductId);


    }
}

public class RetailMilkOrderConfiguration : IEntityTypeConfiguration<RetailMilkOrder>
{
    public void Configure(EntityTypeBuilder<RetailMilkOrder> orderConfig)
    {
        orderConfig.OwnsOne(o => o.RetailOrderDateSpec);
        orderConfig.Metadata.FindNavigation(nameof(RetailMilkOrder.Items)).SetPropertyAccessMode(PropertyAccessMode.Field);

        orderConfig.HasOne<RetailContact>()
            .WithMany()
            .HasForeignKey(i => i.RetailerId);

        orderConfig.HasOne<WareHouse>()
            .WithMany()
            .HasForeignKey(o => o.WareHouseId);

    }
}

请建议我拆分多个Dbcontext并保持Model SnapShot同步的方法。
