EF4 CTP5 Code First approach ignores Table attributes

I'm using EF4 CTP5 code first approach but am having trouble getting it to work. I have a class called "Company" and a database table called "CompanyTable". I want to map the Company class to the CompanyTable table, so have code like this:

[Table(Name = "CompanyTable")]
    public class Company
    {
        [Key]
        [Column(Name = "CompanyIdNumber", DbType = "int")]
        public int CompanyNumber { get; set; }

        [Column(Name = "CompanyName", DbType = "varchar")]
        public string CompanyName { get; set; }
    }

I then call it like so:

var db = new Users();
            var companies = (from c in db.Companies
                            select c).ToList();

However it errors out:

Invalid object name 'dbo.Companies'.

It's obviously not respecting the Table attribute on the class, even though it says here that T开发者_如何学JAVAable attribute is supported. Also it's pluralizing the name it's searching for (Companies instead of Company.) How do I map the class to the table name?

on you class that inherits from DbContext, override the OnModelCreating method

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            modelBuilder.Entity<Company>().ToTable("dbo.CompanyTable");
        }

Forgot to add a reference to the ctp5 dll to my schemas project, it was using System.Data.Linq.Mapping instead.
