While playing around with SOS a little today I took two looks at the output of the command:

!dumpheap -stat

First I ran.

static void Main(string[] args)
{
}  //breakpoint here

Next I added a Console.Writeline.

static void Main(string[] args)
{
Console.WriteLine("Hello!");
}  //breakpoint here

Output of the dumpheap of the first bit of code:

!dumpheap -stat

So 2000+ objects to do... "nothing" and then 2400 additional classes to output one string to the Console.

Seems a lot, but it illustrates how much management it takes to have a managed environment.
