ReadMe.txt file for "Beginning Microsoft Visual C# 2010" (ISBN: 0470502266) By Karli Watson, Christian Nagel, Jacob Hammer Pedersen, Jon D. Reid, Morgan Skinner This download contains zip files for each chapter in the book except for Chapter 1, which is an introductory chapter and has no code. Where necessary, the zip files contain additional ReadMe.txt files with additional, chapter-specific instructions. You can unzip the code wherever you want, but the recommended place to put code (as referenced in the book) is in C:\BegCSharp\ChapterXX, where XX is the chapter number. Visual C# Developer 2010 Express or Visual Studio 2010 is required to compile and run the solutions found in these zip files. Some solutions will only work in Visual Studio 2010, as noted in the book. You can double-click a solution file to open it in the appropriate development environment.
