How to enable Code Analysis for F# projects

As of today, in Visual Studio 2012, the Run Code Analysis command is not available for F# projects.

Code Analysis is a Visual Studio feature for analyzing managed code assemblies and gathering information such as possible design, localization, performance, and security improvements.

Code Analysis can be used as a stand-alone tool with the FxCopCmd command-line application, and it can also be included in automated build processes such as MSBuild.

Enable Code Analysis in MSBuild

To enable Code Analysis in MSBuild, include the following elements in the project file:

<CodeAnalysisModuleSuppressionsFile>GlobalSuppressions.fs</CodeAnalysisModuleSuppressionsFile>
<RunCodeAnalysis>true</RunCodeAnalysis>
<CodeAnalysisRuleSet>My.ruleset</CodeAnalysisRuleSet>

Problem

Unfortunately, even with the above elements, Code Analysis will not run for F# projects during the MSBuild process.

Solution

Edit the Microsoft.CodeAnalysis.Targets file, which is located at: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\CodeAnalysis

Append or '$(Language)'=='F#' at the following locations:

<DefineConstants Condition="'$(Language)'=='C#' ">CODE_ANALYSIS;$(DefineConstants)</DefineConstants>
<PropertyGroup Condition="'$(Language)'=='C#' or '$(Language)'=='VB'">
