Mapping Columns in Entity Framework Code First

I'm having trouble trying to map my EF 4.1 Code First model to a database. Everything works fine when the database match the code exactly, but when I try and map when the columns differ in name then I am running into issues.

I was following a tutorial that must've been built with one of the CTP builds because some of the methods are missing/different.

My model looks like:

public class Dinner
{
    public int DinnerID { get; set; }  
    public string HostedBy { get; set; }
    public DateTime EventDate { get; set; }
    public string Title { get; set; }
    public string Address { get; set; }
}

public class NerdDinners : DbContext
{
    public DbSet<Dinner> Dinners { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        // THIS IS WHAT I TRIED BUT IT IS FAILING
        modelBuilder.Entity<Dinner>().Map(mc =>
            {
                mc.Properties(c => new {
                    colID = c.DinnerID,
                    colTitle = c.Title,
                    colHost = c.HostedBy,
                    colDate = c.EventDate,
                    colAddress = c.Address
                });
                mc.ToTable("tblDinner");
            }
        );
    }
}

I want my table to be:

tblDinners  
    colID  
    colHost  
    colDate  
    colTitle  
    colAddress  

I am getting this error:

The properties expression 'c => new <>f__AnonymousType0`5(colID = c.DinnerID, colTitle = c.Title, colHost = c.HostedBy, colDate = c.EventDate, colAddress = c.Address)' is not valid. The expression should represent a property: C#: 't => t.MyProperty' VB.Net: 'Function(t) t.MyProperty'. When specifying multiple properties use an anonymous type: C#: 't => new { t.MyProperty1, t.MyProperty2 }' VB.Net: 'Function(t) New From { t.MyProperty1, t.MyProperty2 }'.
