I see one Jenkins instance has this step and also "MSBuild SonarQube Runner" section in the system configuration, but another doesn't. I am trying to use Jenkins and SonarQube to analyse C# projects.
I figured out it's only available in SonarQube plugin since v4.4: http://www.sonarqube.org/easy-analysis-of-visual-studio-solutions-with-the-sonarqube-scanner-for-msbuild/
