- ALM used - Azure DevOps
- CI system used - Azure DevOps
- Scanner used - SonarQube Cloud 3.3.0 / SonarCloudPrepare@3 / DotNetCoreCLI@2
- Language - C#
- Error observed - SonarAnalyzer is throwing ArgumentOutOfRange exceptions when analyzing an otherwise harmless-looking C# file.
- Steps to reproduce
- Run the SonarCloudPrepare@3 task in Azure DevOps
- Use DotNetCoreCLI@2
command: 'build'to build a .NET 8 WPF C# project containing only ResourceColors.cs (below)
- Potential workaround: delete line 70
FlagBlueBrushof ResourceColors.cs
OR delete line 11ExcludeFromCodeCoverageattribute
OR delete line 38PeacockBlueDark1
OR delete line 86DarkSkyBlueLightHoverBrush
OR delete line 90IceHoverBrush
OR add a newSolidColorBrushafter line 102
OR delete the blank lines within theColorandSolidColorBrushcode sections, and realign the equal signs within each section
OR delete all end-of-line comments
OR change all integer literals to hex notation (e.g.0xe2)
The workarounds make me suspect this is a bug in SonarAnalyzer.
Errors (also shown in Build log farther below)
