StyleCop analyzes C# source code to enforce a set of style and consistency rules. It can be run from inside of Visual Studio or integrated into an MSBuild project.
StyleCop provides value by enforcing a common set of style rules for C# code. StyleCop will continue to ship with a single, consistent set of rules, with minimal rule configuration allowed. Developers can implement their own rules if they so choose. StyleCop will ship with the ability to seamlessly integrate with Visual Studio, MSBuild, TFS, etc. Developers are free to implement custom code to integrate StyleCop into other development and tooling environments, as described in the SDK documentation.
