Today's $10 deal of the day from APress at http://www.apress.com/9781430235309 is Beginning C# Object-Oriented Programming"Beginning C# Object-Oriented Programming brings you into the modern world of development, as you master the fundamentals of programming with C# and learn to develop efficient, reusable, elegant code through the object-oriented programming (OOP) methodology." 
Here is a summary of my earlier review:This is a good book to learn C# by doing something practical. The book provides an excellent series of hands-on activities.
So should you get a copy for your trainee C# programmers? Yes!
Do I recommend it for people learning C# 2010 on their own? Yes!
Those of you who have written to me for training in C# (assuming the messages were not from BOTS!), should you buy this book - YES!
