MFC Integration with the Windows Transactional File System (TxF)
The Transactional File System (TxF), which allows access to an NTFS file system to be conducted in a transacted manner through extensions to the Windows SDK API. MFC 10, has been extended to support TxF and related technologies. This support allows existing MFC applications to be easily extended to support kernel transactions.

Implementing a WCF Message Contract
WCF implementations normally take two different approaches; a Document style or an API style. Document style implementations are more flexible and often easier to extend and version. Also, Document style or rather, Message Contract service implementations, work well between systems with a shared message assembly. Jeffrey Juday guides you through architecting a WCF Message Contract implementation.
