Entity Framework, CTP5, SQLServerCompact, missing Database.SetInitializer

Question

I've installed EFCodeFirst 0.8 (CTP5) and EFCodeFirst.SQLServerCompact 0.8.84821. I've updated the references to EntityFramework and System.Data.SqlServerCe.Entity.dll. My project compiles and runs, with one exception: I can not call Database.SetInitializer.

Here is how my code looks:

using System.Data.Entity;

namespace Recipes.Models
{
    public class RecipesEntities : DbContext
    {
        public RecipesEntities()
        {

            System.Data.Entity.Database.SetInitializer<RecipesEntities>(new SampleData());
            //Database.SetInitializer<RecipesEntities>(new SampleData());
        }

        public DbSet<Category> Categories { get; set; }
        ...
    }
}

and the error I get is

The type or namespace 'SetInitializer' does not exist in the namespace 'System.Data.Entity.Database

Indeed, it does not show up in the Intellisense. However, as I said - if I comment out the line that calls SetInitializer, the project compiles and runs. I can not test it properly though cause most operations depend on some seed data in the DB.

What could be the reason for such behaviour?
