Scan c# projects

In the second command below do we have to give 4.6 as target framework?
In this [link] it is said that NET Framework v4.6+ with either Visual Studio…
In addition, what is the lowest framework version Sonar supports in c# analysis?

Our server version is community 7.0 and c# plugin version is 5.8 (build 645 .

  1. SonarScanner.MSBuild.exe begin /k: "project-key"
  2. MSBuild.exe /t:Rebuild
  3. SonarScanner.MSBuild.exe end

Thank You
