I wonder, if they can introduce nullable DateTime, why don't they add an overload to TryParse which accepts nullable DateTime ?

System.Diagnostics.Debugger.Log(0,"", "Current thread is: " + Threading.CurrentThread.GetHashCode());

int tempInt = Threading.CurrentThread.GetHashCode();
string tempStr = string.Concat("Current thread is: ", tempInt.ToString());
System.Diagnostics.Debugger.Log(0,"", tempStr);

But now it occurs to me that I have no idea if my method is guaranteed to be executing on the same thread all the way through. Is there some chance that after AnotherMethodWhereWorkIsDone() executes, my handler will be running on a different thread than when I shapshotted it above AnotherMethodWhereWorkIsDone()?
