Linq Query ToList() Acting Up

Question

var v = object.where(a => a.date > DateTime(2000,1,1,));
list = v.ToList();

Ok, so for the following code, i have break points set up on each line. When i get to the first line, I run the code (F5) until it reaches the 2nd line. When i step forward (F11) from the second line, it returns to the first line. When I run the code (F5) it doesn't make it to the second line and throws an error.

Is my linq query wrong, or is something else not working? I'm totally confuzored.
