Response to: Hello World in WinFx?

Since WinFX is a superset of the .NET Framework, the answer is exactly the same as it is in .NET:

class App
static void Main()
System.Console.WriteLine("Hello, world");

Of course if you want a non-console version, then you'd have to say whether you want an Avalon, ASP.NET, or Windows Forms version of Hello world. But the above is the simplest.
