I am using SonarQube community v7.7 and when I used to scan the code earlier the C# code would be evaluated and results displayed on dashboard. However, now when we scan the code only CSS and HTML code is being scanned. We can see a message " Quality profile : Stop using ‘ Sonar way’(cs) . We cannot find the quality profile with the similar name in our instance when we search now.
Since the profile has disappeared, it sounds like someone might have uninstalled the C# analyzer. Since you’re way behind in versions anyway, why not go ahead & upgrade to the latest release, 8.6, which will come complete with C# analysis and a default profile?
