Hello community.

This time I want to ask about the problem I have when analyzing a NET CORE 6.0 project where when executing it throws the error

“Your project contains C# files which cannot be analyzed with the scanner you are using. To analyze C# or [VB.NET](http://VB.NET), you must use the SonarScanner for .NET 5.x or higher, see [SonarScanner for .NET | SonarQube Docs](https://redirect.sonarsource.com/doc/install-configure-scanner-msbuild.html)”

any ideas?

Thank you  
Dario Flores

Hey there.

Have you read the documentation that the error message links?

Hi Colin.

First of all thanks for replying.

If I read this documentation:  
\*)I have the requirements.  
\*) I have dotnet-sonarscanner  
\*) Task sonar DevOps Extension 5.8.0

I’m running it from DevOps in a pipeline.

something I didn’t do?

Thank you

Good.

I continue with the problem, and I pass more information to see if someone can help me.

On the one hand, the pipeline logs tell me:

# ##[section]Starting: Run Code Analysis

Task : Run Code Analysis  
Description : Run scanner and upload the results to the SonarQube server.  
Version : 5.8.0  
Author : sonarsource

and on the other it keeps throwing this:

WARN: Your project contains C# files which cannot be analyzed with the scanner you are using. To analyze C# or [VB.NET](http://VB.NET), you must use the SonarScanner for .NET 5.x or higher, see [Installing the scanner | SonarQube Server 2025.5 | Sonar Documentation](https://redirect.sonarsource.com/doc/install-configure-scanner-msbuild.html)

I really don’t understand what the problem is ☹
