Yes, it really did get fixed in RTM. The cut-off date for bug fixes that made it into the RC without any additional effort was around the beginning on April.

I believe I am having this issue with .NET 4.5 RC as well. Once I uninstalled 4.5 and reinstalled 4.0 the issue went away.

It doesn't appear to be solved in release candidate.
Do you plan a fix before RTM ?

Yes, the RTM version of .NET 4.5 will have the fix. As a work-around simply use the emptry string literal, rather than String.Empty inside instance constructors or instance field initializers. Sorry for not mentioning that, but I assumed you had already figured that out, due to your very detailed repro source.

With regards to the "future version of the product" does this mean the RTM version of .net 4.5. Our concern is currently our solution built on top of .net 4.0 is broken with the presence of .net 4.5 on a system causing us to pull the beta off of our development test environments. We would like to continue using the Beta version to discover any more issues before RTM however we are blocked at the momment becuase of this issue. We also need to understand if our solution can be supported with the presence of .net 4.5 once release.
