One easy way of doing this for your own custom-types would be to increment and track some counter in their finalizers.

e.g.

public class MyCustomType
{
    public static int NumFinalizersCalled;

    ~MyCustomType()
    {
        Interlocked.Increment(ref NumFinalizersCalled);
    }
}

In the Visual Studio debugger you can use the SOS library in the immediate window. There are several GC methods that give you the information you need. I don't know if this is what you want, but it is a starting point.
