Announcing the release of Microsoft Source Analysis for C#Source Analysis is similar in many ways to Microsoft Code Analysis
FxCop, but there are some important distinctions. FxCop performs its analysis on compiled binaries, while Source Analysis analyzes the source code directly. For this reason, Code Analysis focuses more on the design of the code, while Source Analysis focuses on layout, readability and documentation. Most of that information is stripped away during the compilation process, and thus cannot be analyzed by FxCop.
