[SDanehy]

When running Stryker locally it is looking for the AssemblyInfo.cs file in the .net6.0 folder but the project has a target framework of .net8.0

Logs
dotnet stryker -p PROJECT_NAME.csproj --target-framework 'net8.0'

Additional context
I found this stack overflow article with the same issue but it does not have a solution yet:

thanks for reporting this. Could you please share the project file (.csproj)?
Are you certain this file is not explicitly referred in the project (it happens sometimes)?
Are you certain there is no configuration that targets net6.0?
