In previous versions of Visual Studio case sensitivity setting were persistent: they carried over from one search session to another. Also, case sensitivity setting used in last regular search applied to incremental search feature (CTRL+I).
This is no longer the case in VS2012 ("Express for Desktop" version). The incremental search is always case INsensitive, regardless of what settings were used in the previous regular search.
So, how do I switch incremental search to case sensitive mode?
