False positive of csharpsquid:S1116

Hi, I’ve been seeing this false positive as well and thought I’d hop in to provide some additional data points.

I tried building a minimal repro (See GitHub) for it using SonarAnalyzer.CSharp (which is currently the latest version) and noticed that, using Rider with the SonarLint Plugin, I would only get the false positive from the plugin, not from the analyzer:



Notice how both the plugin and the analyzer (on build) report S125 because of the commented out line of code, but the analyzer does not report S1116, only the plugin.

So it seems to be a plugin-specific thing i guess? Hope these observations help in finding the cause :slight_smile:

Here’s the info from Rider’s about dialog:
