What is FxCop?

FxCop is a free code analysis tool developed by Microsoft, use to analyze MSIL (Microsoft Intermediate Language) generated from any managed language (including C# and VB.NET).

FxCop is a standalone .NET 2.0 application, downloadable from the locations referenced below. A modified version of the FxCop codebase is integrated into Microsoft Visual Studio 2005 and 2008. While the rulebase for each is mostly the same, there are notable differences between the two (see the Rules comparison spreadsheet below), and the compiled format for custom rules is different; thus, one cannot generally develop custom rules that can be used natively in both contexts.

Resources

Tool, Documentation and Community

• Download - FxCop v1.35
• Download - FxCop v1.36 (beta)
• Download - [ FxCop v1.32] - necessary if you wish to perform analysis of code written in Visual Studio 2003 or earlier
• Download - Rules comparison spreadsheet - documenting the rules differences between those shipped with FxCop and the Visual Studio Code Analysis feature
• Documentation - FxCop - MSDN documentation for FxCop
• Forum - Visual Studio Code Analysis and Code Metrics - MSDN forum to discuss issues and ideas regarding FxCop and the Visual Studio Code Analysis feature
• Wikipedia - FxCop article
• Blog - Microsoft Code Analysis Team blog - addresses both the standalone FxCop tool as well as the Visual Studio Code Analysis feature
• Blog - Dave's Box - personal blog written by a member of Microsoft's Code Analysis team

Custom Rules and other third-party Enhancements

• JSL FxCop (CodePlex) - open-source utility to help build custom FxCop rules, as well as many custom rules.
• Community Static Analysis Rules (CodePlex) - "a community-based project for creating a set of static analysis rules to extend those provided by the FxCop team."
• TeachNaGeamhradh FxCop Rules (SourceForge) - "A growing collection of rules and experimentation with FxCop to provide a comprehensive list of rules that are useful against the .Net assemblies."
• Lephone FxCop Rules (CodePlex) - a small set of custom rules
• CustomFxCop (CodePlex) - implements "...new rule sets to check variable naming conventions in a project. This will really help projects to automate their code review process."
• findbugs-FxCop - "This project will produce custom rules for FxCop, that will look for coding mistakes similar to those found by FindBugs, such as infinite recursive loops and ignored return values."
• fxcop rule : checking for IDataReader in method parameters - a single FxCop rule in source code form
• FxDeputy - "This project is of use to anyone writing rules for the FxCop checker for .NET. This provides a framework that will allow you to tag tests with attributes that will provide you with control of what tests are run against your rules."
• FxCopUnit - "A framework for integrated FxCop rule testing"
• FxCop Delta (CodePlex) - "a custom check-in policy for Visual Studio Team System that runs FxCop rules before performing a check-in."
• FinRad Statistics Collector for FxCop (CodePlex) - "...intended to help development teams to track the progress of an FxCop backlog cleanup effort."
• (CustomRules in FxCop - DEAD CodePlex project)

Similar Tools for .NET code analysis

• Agent Smith Plugin - "Agent Smith is C# code style validation plugin for ReSharper (Visual Studio plugin)."
• Agent Johnson Plugin - "Plugin for JetBrains ReSharper", performing limited code analysis, refactoring and fixups on C# code.
• Smokey (Google Code) - tool similar to FxCop for analysing managed code; has 220 separate rules.
