StyleCop
StyleCop is an open source static code analysis tool from Microsoft that checks C# code for conformance to StyleCop's recommended coding styles and a subset of Microsoft's .NET Framework Design Guidelines. StyleCop analyzes the source code, allowing it to enforce a different set of rules from FxCop (which, instead of source code, checks .NET managed code assemblies). The rules are classified into the following categories:
- Documentation
- Layout
- Maintainability
- Naming
- Ordering
- Readability
- Spacing
StyleCop includes both GUI and command line versions of the tool. It is possible to create new rules to be used.
StyleCop was re-released as an open source project in April 2010 at http://stylecop.codeplex.com.
