// There is no guarantee that WeakReference objects will be collected after GC.Collect().
// The bottom line is, compiler generated temps for objects created locally (within the
// same function), castings, boxing/unboxing will get their lifetimes extended to the
// end of the function.
//
// All these are due to changes related to the MinOpts feature made during the
// Silverlight/Arrowhead timeframe. For more information, see DevDiv Bugs 170524.
//
// Many of these behaviors are not documented. If any of the underlying implementation is
// changed, the tests will need to be updated as well.
