MVC 3 Session.Abandon (), called before setting TempData ["myvalue"] = "foo", causes the next controller to have TempData as null

Question

I have a controller logic that is looking for: session value

 //checks value null etc..  for existing record in session memory.
 Session["certnum"]  

Then in the controller I decided to have a condition in which:

 //is called to initiate a New Record that will be created.
 Session.Abandon();

However, in procedural encoding, this is Session.Abandon (); precedes the creation of TempData ["myobject"] = "foo", and after passing the code TempData in the next window shows my value, and everything seems to be good. Then, when redirecting to another controller:

return RedirectToAction("ChildInfo", "NewRecord");
