False positive of csharpsquid:S1116

[dmitriy.vorobey1 (Dmitry)]

Please provide

• Operating system: MacOS
• SonarLint plugin version: 10.1.1.77150
• Programming language you’re coding in: C#
• Is connected mode used: No

And a thorough description of the problem / question:
Code:
new List<int>().Should().BeEquivalentTo([5]);

Result:
False positive rule activation: csharpsquid:S1116 (Empty statements should be removed)
Expected result:
no rule activation because there is no redundant semicolon and code is valid

Hi @dmitriy.vorobey1! Welcome to Sonar community.
Your issue seems very similar to this one.

Are you using the latest version of the .Net 8 SDK from November 14?

[dmitriy.vorobey1 (Dmitry)]

Hi Cristian,
Yeap, they are really similar. But I didn’t catch a solution.

My SDK version :
dotnet --version
8.0.100
Also I double checked sonar lint plugin version: 10.1.1.77150.

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 9.15.0.81779 (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

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