Ignore rule from the project tab

it will be much easier to ignore rules from the issues page

its not comfortable to do it from the administration page


In the screenshot you shared, the issue was raised by an external analyzer (look at the ROSLYN badge), not by an analyzer provided out of the box by SonarQube.
For such issues, raised by 3rd party analyzers, the corresponding rule can only be disabled on the 3rd party analyzer itself, not in the SonarQube UI.

Even for regular rules provided by SonarQube, providing a possibility to disable a rule on the spot, at issue level would be dangerous because this would impact a Quality Profile that may be used by another projects.

If you want to silent that specific issue, maybe you should consider marking the issue as " False-Positive" or “Won’t Fix”.
