SonarQube runner throws org.sonar.runner.impl.RunnerException

Question

SonarQube runner throws org.sonar.runner.impl.RunnerException when I try to analyze .Net/C# project on machine where Visual Studio is not installed.

Here is the log snippet:

Is Visual Studio required to analyze C# code?

Answer 1

Visual Studio is not required to analyze C# code, however you will need a pretty recent .Net runtime (4.5 as of writing).

You might also want to have a look at the newer integration with TFS and MSBuild.
