There is a bug mentioned in David Broman's response to this thread:

Can someone say exactly what version of the CLR this was fixed in? In that thread he says it was "fixed in the CLR 4.5 beta" but if I understand CLR versioning correctly (I may not) it never got to 4.5 but instead stayed on 4.0.30319.* with patch fixes after that. I want to be able to identify if our customers are running into this issue or something else but to do that I need to know what to look for to identify whether or not they have the fix referred to in the above post.
I believe the .NET 4.5 Beta (Consumer Preview) was CLR version 4.0.30319.17379, so perhaps it was fixed in that version and up but I want to make sure before I commit to asking my users experiencing problems to update.
