"Beginning C# Game Programming" is Ron Penton's third effort in game book-authorship. It's a ground-up tutorial on the C# programming language, starting from the obligatory "Hello World" program and ending with a pretty rudimentary "spaceship at the bottom of the screen shooting at things coming down at you" game called "Generic Space Shooter 3000".
If you're already an old hand at similar languages like Java or C++, then the first half of the book won't be much more than a refresher for you. The first half of the book covers simple screen output, followed by primitive types, operators, looping, classes, arrays and file streams. It covers these topics fairly quickly (all in about 120 pages), so you won't be spending much time on each topic. Apart from one significant exception, the language tutorial is well-organized.
The "significant exception" raises its head with chapter 6 (creating a project). After spending 120 pages learning how to write, compile, and execute small bits of C# code, chapter 6 shows you how to set up a project in SharpDevelop (a free C# programming environment). If you need help compiling your code in chapters 1-5, the only help you'll get is a brief mention of Visual Studio.NET, SharpDevelop, or the C# command-line compiler. If you invest in a copy of "Beginning C# Game Programming", I recommend that you read chapter 6 first. Then go back to chapters 1-5. Finally, head over to chapter 7 and build yourself a space-shooter for the rest of the book.
The space shooter chapters are well-done, with good coverage of doing directX graphics in C#. The topics covered are a bit large for such a simple example game (alpha-blending, force-feedback, direct3D), but this is done with the understanding that you'll be wanting to write a more significant game than "Generic Space Shooter 3000" by the time you're done with the book.
If you want a good "ground-up" start with C# game programming, "Beginning C# Game Programming" is a good start. It takes you from the very beginning to a complete arcade game.
Just don't read it in order.
