**Title:** SonarLint not detecting issues locally that appear on SonarQube server (C# project) **Operating system:** macOS (Apple Silicon) **SonarLint plugin version:** - SonarLint for VS Code: v4.40.0 - SonarLint for Rider: 2025.3 (latest available) **IDE version:** - VS Code: Latest - JetBrains Rider: 2025.3 **Programming language:** C# (.NET 8) **Is connected mode used:** Yes, Connected Mode is configured and synced with SonarQube server **SonarQube Server version:** SonarQube Enterprise Edition 2025.5.0 (build 113872) * * * **Problem Description:** SonarLint in both VS Code and Rider is not detecting code quality issues locally, even though the same issues are correctly detected when running the full SonarQube scanner (both locally and in CI/CD). **Example:** Rule **S2930** (“IDisposables should be disposed”) is active in the quality profile and appears on the SonarQube server after scanning, but SonarLint shows **0 issues** when analyzing the same file locally. \*\*Code example (LambdaContextExtensions.cs): \*\* `public static CancellationToken CancellationToken(this Amazon.Lambda.Core.ILambdaContext context)` `{` `var timeout = context.RemainingTime.Subtract(TimeSpan.FromMilliseconds(500));` `var cts = new CancellationTokenSource(timeout); // S2930 should trigger here` `return cts.Token;` `}` **SonarLint Analysis Output (from Rider logs):** ```auto [sonarlint-analysis-scheduler] INFO sonarlint - Starting analysis with configuration activeRules: [337 csharpsquid, 24 css, 49 Web, …] inputFiles: [LambdaContextExtensions.cs (UTF-8)] [Report about progress of OmniSharp analyzer] INFO - 1 source file to be analyzed [Report about progress of OmniSharp analyzer] INFO - 1/1 source file has been analyzed [sonarlint-analysis-scheduler] INFO sonarlint - Analysis detected 0 issues and 0 Security Hotspots in 90ms ``` The OmniSharp analyzer completes successfully but finds nothing. ---

Hi, Welcome to the community and thanks for this report! Can you provide [verbose logs](https://docs.sonarsource.com/sonarqube-for-vs-code/resources/troubleshooting) from IDE startup to where this (doesn’t) happen?   Thx, Ann ---

Hi Ann, This happens either in vs code or in rider, where this does not happen is in sonarqube server. To clarify, sonarqube server is good, shows the errors and warnings, locally does not show anything. What can I provide you to better help me? Thanks! ---

Hi, I still need verbose logs from startup. Either or ideally both IDEs.   Ann ---

Hi @Walter_Palma Unfortunately I am not able to reproduce this issue. Could you please try the latest version of the plugin and provide full logs? You can send them in a private message to me ---

We are experiencing kind of the same issue. However found something additional: When opening vscode, with the file directly (basically having it closed while file in editor), it DOES find the issues. Closing the file and reopening it (or basically any other file), it does not detect any issues anymore. I will add verbose logs [sq-logs after file closed and reopened.txt](https://community.sonarsource.com/uploads/short-url/t547z9lz8n8F6rJleWKzqU0pLN6.txt) (50.6 KB) [sq-logs after startup.txt](https://community.sonarsource.com/uploads/short-url/6fzfUpOLyt7MYDzX2UkLcxXxPPV.txt) (2.0 MB) the scan on the very same file with the very same settings found 3 issues at first, and then none ---

as a layman, it seems, that org.sonarsource.sonarlint.omnisharp.protocol.OmnisharpResponseProcessor is not executed on scans later on anymore. ---

My issue seems to be new and bound to Version 5.2. Version 5.1 works without that problem ---

Hi @Leopold_Lerch, Thanks for reaching out. I see you opened a new [thread](https://community.sonarsource.com/t/issues-in-c-files-not-found-when-not-opend-during-extension-startup/181882), I suggest we continue the discussion there, I think your problem is not related to the current thread. Thanks! ---

sure, as I found out, that it is kind of new because of its connection to v 5.2, I opened the new thread.
