As described in this earlier and extremely well written bug report (http://social.msdn.microsoft.com/Forums/en-US/vsdebug/thread/c118df4d-01b4-4e1f-9cc2-4a7626c9fe93), certain natvis definitions will cause visual studio to maintain an open reference to the pdb file for that project after debugging. This means that after debugging, I will receive LNK1201 until I restart visual studio.I am now also experiencing the same issue and I do not use 'Synthetic' fields, meaning it wasn't just that.So either I lose out on all nice visualization I was offered or I am stuck restarting visual studio every time I debug.
