For today only (that’s Sunday, August 15th), Manning is offering the pair of their books, C# in Depth, Second Edition and Azure in Action for the price of one! Just use the discount code dotd0815 in the Promotional Code box when you check out. You can order the final book in either dead-tree or PDF format.
Both these books are MEAP books – that’s short for Manning Early Access Program, a chance for you to get in-progress and final editions of books currently being written.
