After upgrading Community Edition from version 10.7 to 25.3.0 we are missing the rule S5773.
It is still present in the version 2025.2 of the Developer Edition.
Also, I found the rule in the current code of sonar-dotnet and its sonar-way profile.
Hi,
This rule was removed in version 24.12. As usual, the communications from SonarSource were rather ambiguous, requiring some time for me to locate the information.
From SonarQube Community Build 24.12.0.100206 released
