Static program analysis software

StyleCop Original author Microsoft Developers Jason Allor, Andy Reeves, Chris Dahlberg Stable release 5.0.6329.1 / April 30, 2017; 9 years ago (2017-04-30) Written in C# Operating system Microsoft Windows Platform .NET Framework Type Static code analysis tool License Microsoft Public Licence Website github.com/StyleCop Repository github.com/StyleCop/StyleCop

**StyleCop** is an [open-source](/source/Open-source_software) [static code analysis](/source/Static_code_analysis) tool from [Microsoft](/source/Microsoft)[1] that checks [C#](/source/C_Sharp_(programming_language)) code for conformance to StyleCop's recommended coding styles and a subset of Microsoft's .NET Framework Design Guidelines. StyleCop analyses the [source code](/source/Source_code), allowing it to enforce a different set of rules from [FxCop](/source/FxCop) (which, instead of source code, checks [.NET](/source/.NET_Framework) [managed code](/source/Managed_code) [assemblies](/source/Assembly_(CLI))).[2][3] The rules are classified into the following categories:

- Documentation

- Layout

- Maintainability

- Naming

- Ordering

- Readability

- Spacing

StyleCop includes both [GUI](/source/GUI) and command-line versions of the tool. It is possible to add new rules to be applied.

StyleCop was originally developed by Jason Allor as a Microsoft internal tool, and was released externally as an open-source project in April 2010 on [CodePlex](/source/CodePlex).

StyleCop 4.7.55 (November 10, 2016) is compatible with Visual Studio 2008, 2010, 2012, 2013, and 2015.[4] (Microsoft Visual Studio Extension)

StyleCop began a move to [GitHub](/source/GitHub) in December 2014,[5] and the last change applied to the CodePlex edition was November 11, 2016.[6]

StyleCop 5.0.6329.1 (April 30, 2017) works with Visual Studio 2012, 2013, 2015, and 2017.[7] (Windows Installer)

Development is stopping. A named successor is StyleCopAnalyzers, for Visual Studio 2015 and later.[8]
