Since ESQL was considered an advanced use case, there is no straightforward API from DbContext. You can access the ObjectContext that backs your DbContext to do what you want:

((IObjectContextAdapter)context).ObjectContext.CreateQuery("esql..")

As suggested there, you can also add a method ( or property) ObjectContext to your context class:

public class BloggingContext : DbContext
{
    public DbSet Blogs { get; set; }
    public DbSet Posts { get; set; }

    public ObjectContext ObjectContext()
    {
        return (this as IObjectContextAdapter).ObjectContext;
    }
}
