This document discusses advanced code analysis in .NET. It introduces various static and dynamic analysis tools that can analyze source code, detect issues, and provide visualizations and metrics. These tools include FxCop, StyleCop, ReSharper, and Gendarme for static analysis as well as dotCover, OpenCover, and nCover for dynamic analysis. The document argues that while code analysis faces some objections, taking a "blueprint, analyze, improve" approach and using the right tools can provide benefits like increased code quality.
