Rider Showing Invisible Errors without any error in project.

Hello, 

Sorry for the late response. 

Regarding this issue, could you please try clearing the caches first: File | Invalidate caches => Invalidate and restart? 

If this doesn’t help

1. Do you use source generators in the project? There is a known issue that happens with source generators: RIDER-130867 Invisible errors in the All Solution Files tab. Errors are from generated sources. 

2. If this is not the case, the issue needs to be investigated on a case-by-case basis. Please report it on our issue tracker, with the following logs:

1. Go to Help | Diagnostic tools | Choose Trace Scenarios;
2. Enable the trace scenario for SWEA, SWEADeepDependencyAnalysis, and Daemon;
3. Reproduce the issue;
4. Collect the full log bundle via Help | Collect Logs and Diagnostic Data;
5. Disable the trace scenarios enabled;
6. Attach the resulting log bundle to this ticket or upload it to our server and share the ID.

Thanks,

Tom

sry, i forget to say this, this is maui source-generator file's error but this is not showing in IDE except error count, i disable the ‘show source-generator error’ in rider settings. 

Thanks for the update. This should be the same issue mentioned above. You can subscribe to receive further updates. 

Meanwhile, you can try adding *.g.cs to the file masks under "Inspection Settings" -> "Elements to Skip" as a workaround. 

Thanks,

Tom
