Convert Lambda from C# to VB.NET

How would I translate this C# lambda expression into VB.NET ?

query.ExecuteAsync(op => op.Results.ForEach(Employees.Add));


using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Collections.ObjectModel;
using IdeaBlade.Core;
using IdeaBlade.EntityModel;



namespace SimpleSteps
{
    public class MainPageViewModel
    {
        public MainPageViewModel()
        {
            Employees = new ObservableCollection();
            var mgr = new NorthwindIBEntities();
            var query = mgr.Employees;
            query.ExecuteAsync(op => op.Results.ForEach(Employees.Add));
        }



    public ObservableCollection<Employee> Employees { get; private set; }
}




}

I found the solution..

query.ExecuteAsync.Results.ForEach(Sub(o) Employees.Add(o))

Hope this helps to others

Starting with 2010, VB10 supports non-functional lambdas.

query.ExecuteAsync(Sub(op) op.Results.ForEach(Employees.Add))
