I'm very happy that Microsoft is committed to VB.NET have the same features as C#.
One feature I use extensivle in C# is collection initializers. I've just noticed that VB.NET supports these but not for read-only class properties.
I found at http://msdn.microsoft.com/en-us/library/dd293617.aspx that if a collection has a an Add method, it is used to initialize the variable. This should also apply to read-only collection properties.

Here is compilable C# code showing the feature working:

using System;
using System.Collections.Generic;

namespace ConsoleApplication3
{
class Class1
{
private readonly List<Int32> list = new List<Int32>();

public List<Int32> ListProp
{
get
{
return this.list;
}
}
}

class Program
{
static void Main(string[] args)
{
// a collection initialization
var list = new List<Int32> { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

// a read-only collection property initialization
var class1 = new Class1
{
ListProp = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }
};
}
}
}
