Have you heard of the LINQ project? I recently came accross it.
Since .NET 3.x is going to support Lambda expressions, .NET developers will introduce LINQ (Language Integrated Query) which supports SQL-like statements for arrays and collections.
Along with it are coming XLing and Dling for creating classes which integrate seamlessly with an XML or Database schema respectively.
Here are some examples:
public void Linq6() {
    int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };

    var numsPlusOne =
        from n in numbers
        select n + 1;
    Console.WriteLine("Numbers + 1:");
    foreach (var i in numsPlusOne) {
public void Linq88() { 
   List products = GetProductList();

   var categories = 
      from p in products 
      group p by p.Category into g 
      from maxPrice = g.Group.Max(p => p.UnitPrice) 
      select new {Category = g.Key, MostExpensiveProducts = g.Group.Where(p => p.UnitPrice == maxPrice)}; 

   ObjectDumper.Write(categories, 1);

The LINQ Project:

You can download a CTP version of Visual Studio Orcas (the next Visual Studio release), which includes .NET 3.5 and allows you to develop with LINQ.

This is a new direction for OO languages and independently of whether it will be a success or a failure (personally i think it's a great idea) it's important to keep up with the times.
