Yes, more details about “Pull request decoration” can be found in the docs for SonarQube Cloud and for SonarQube Server.
Sorry, my response wasn’t clear. Indeed, NOSONAR was available on Visual Studio, but due to a technical limitation, it wasn’t recognized in C and C++ analysis. These limitations were addressed in the tickets I linked in my previous response (community announcement here). We also have a card on our product board to improve the specificity of // NOSONAR, see here.
Best regards,
Michael
