Question

I am trying to implement the following code to map a database to a POCO that has slightly different Property names then the corresponding columns, and a slightly different class name than the table name.

Here’s the article

The problem is there is no method called MapSingleType. I have the following two methods available:

public EntityTypeConfiguration<TEntityType> Map<TDerived>(Action<EntityMappingConfiguration<TDerived>> derivedTypeMapConfigurationAction) where TDerived : class, TEntityType;

public EntityTypeConfiguration<TEntityType> Map(Action<EntityMappingConfiguration<TEntityType>> entityMappingConfigurationAction);

However, I can’t find any examples of how to use them and I’m hoping to find the MapSingleType method since that works perfect for the very large number of columns I have to map.

I have downloaded CTP4 from here

And I am using EF 4.0.3

Here is the code I have so far:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations;
using PlayingWithEF.DAL.CLS.Classes;
using System.Data.Entity.ModelConfiguration;

namespace PlayingWithEF.DAL.CLS.Context
{

    public class CLSContext : DbContext
    {
        public DbSet<Listing> Listings { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Listing>().Map(...?)
        }
    }
}

You’re going to have to map each property individually:

modelBuilder.Entity<Listing>()
   .Property(l => l.YourProperty)
   .HasColumnName("PropertyName");

modelBuilder.Entity<Listing>()
   .ToTable("TableName");
