We are very excited to announce the release of a new developer tool from Microsoft, Source Analysis for C#. This tool is known internally within Microsoft as StyleCop, and has been used for many years now to help teams enforce a common set of best practices for layout, readability, maintainability, and documentation of C# source code.
StyleCop is similar in many ways to Microsoft Code Analysis (specifically FxCop), but there are some important distinctions. FxCop performs its analysis on compiled binaries, while StyleCop analyzes the source code directly. For this reason, FxCop focuses more on the design of the code, while StyleCop focuses on layout, readability and documentation. Most of that information is stripped away during the compilation process, and thus cannot be analyzed by FxCop.
The ultimate goal of StyleCop is to allow you to produce elegant, consistent code that your team members and others who view your code will find highly readable. In order to accomplish this, StyleCop does not allow its rules to be very configurable. StyleCop takes a one-size-fits-all approach to code style, layout, and readability rules. It is highly likely that you will not agree with all of the rules and may even find some of the rules annoying at first! However, the majority of teams using this tool within Microsoft have found that after a short adjustment period, they came to appreciate the rules enforced by StyleCop, and even began to find it difficult to read code not written in this style.
StyleCop comes with a set of default rules analyzers covering approximately 200 best practice rules. These rules are full compatible with the default layout settings in Visual Studio 2005 and Visual Studio 2008.
Specifically, these rules cover the following, in no particular order:
After installation, StyleCop can be run from within the Visual Studio IDE, and can also be integrated into MSBuild-based command line builds.
