The C# Ecosystem is a Set of Plugins

The C# Ecosystem offers the following plugins:

Mandatory plugins:
- .NET Core: the core plugin that defines API used by every other plugin in the ecosystem.
- C# Core: the plugin that parses C# code source, computes metrics and detects copy-paste.
Optional plugins adding features from external tools:
- .NET FxCop: launches FxCop analyses to detect issues related to potential bugs, tight coupling, globalization, etc.
- .NET Gendarme: launches Gendarme analyses to detect issues related to coding bad practices, smell detection, performance, etc
- .NET Gallio: launches Gallio to run tests and gets execution report as well as coverage report (using PartCover or OpenCover or NCover or ...).
- .NET NDeps: launches a dependency parser tool, built on Mono Cecil, to get dependency data between assemblies and classes.
- C# StyleCop: launches StyleCop analyses to detect issues mainly related to coding style (formatting, comments, ...).

Requirements

The C# Ecosystem has the following requirements on top of the SonarQube ones:

Your C# code base must be developed with Visual Studio, and thus must contain a ".sln" file (.NET Solution).
If you want test metrics, unit tests must be isolated from the main code base in dedicated Visual Studio Projects. Also the test framework must be compatible with Gallio.

Supported versions are:

C# language	Up to 5.0
.NET framework	2.0, 3.5, 4.0 and 4.5
Silverlight	3, 4 and 5
Visual Studio	Tested with VS 2008, VS 2010 and VS 2012 ".sln" files. Older versions may also be supported (feel free to give feedback)

Installing the C# Ecosystem Plugins

Install the .NET and C# plugins from the Update Center
- Prior to SonarQube 3.5: you need to click on the Install button of all the 7 plugins
- Since SonarQube 3.5: you just need to click on the Install button of the C# group, this will install everything including the .NET plugins
Restart the SonarQube server

Installing the External Tools

Depending on which plugins you chose to install, you may need to install the corresponding external tools. If you can, we advise you to install the same versions as the one we use for testing (i.e. the one in bold in the below table).

SonarQube analysis is not necessarily performed on the same machine as the one running your SonarQube server. This means that you can run SonarQube on a Linux box and run analyses on Windows boxes. The external tools have to be installed on the Windows boxes where analyses are performed.

Tool	Install required if plugin selected?	Web site / download / install guide	Supported versions (Tested one in bold)
FxCop	YES	http://www.infoq.com/news/2010/06/FXCop-10	1.36+ (10.0)
StyleCop	NO, StyleCop 4.7 binaries are embedded in the plugin.	http://stylecop.codeplex.com	4.6+ (4.7)
Gendarme	NO, Gendarme 2.10 binaries are embedded in the plugin.	http://www.mono-project.com/Gendarme	2.10+ (2.10)
Gallio	YES	http://www.gallio.org	3.1 Update 2 + (3.2.3)
PartCover	YES if you want to use PartCover as the coverage engine. Since PartCover is no longer maintained, OpenCover is preferred.	https://github.com/sawilde/partcover.net4 (click on the "Downloads" button)	2.2, 2.3 and 4.0 (4.0)
NCover	YES if you want to use NCover as the coverage engine	http://www.ncover.com	3.0 (3.0) Version 4 is currently not supported.
OpenCover	YES if you want to use OpenCover as the coverage engine. OpenCover is preferred to PartCover. You need .NET 4 installed on your build machine in order to use OpenCover.	https://github.com/sawilde/opencover	1.0.X, 2.0.X, 4.0.X (4.0.1118)
JetBrains dotCover	YES if you want to use dotCover as the coverage engine.	http://www.jetbrains.com/dotcover/	1.X, 2.X (1.2 & 2.0)
NDeps	NO, binaries are embedded in the plugin.	https://github.com/grozeille/DependencyParser

Some notes:

These external tools need the .Net framework to be installed. FxCop10 needs .Net 4 but the other ones runs fine with .Net 3.5.
StyleCop plugin relies on MsBuild to run the analysis.
Former versions of the StyleCop plugin (1.3 and before) were embedding StyleCop 4.4, whereas new versions (1.4+) are embedding StyleCop 4.7.34.0.
