Excellent book on writing quality code

Here is a great book that I came across on Microsoft Australia's website. Its got some great information about writting quality code. You can download the book from here (its free). Interestingly it uses a new format "DNL" and you need the reader which you can download from http://www.dnaml.com/. (The DNL format makes for an interesting electronic reading experience). Topics include: Test-driven development Performance tuning managed applications Code quality tools for native development Application Threat Modeling Code analysis with FXCop Web application load test Customising check-in policies
