NullReferenceException after 5.1.0 update

[alltho]

Running a pipeline this evening with the install cmd:

- task: CmdLine@2
  displayName: 'Install CycloneDX CLI'
  inputs:
    script: |
      dotnet tool install --global CycloneDX

And running the tool with

- task: CmdLine@2
  displayName: 'Generate CycloneDX BOM'
  inputs:
    script: |
      dotnet-CycloneDX ./src/MySolution.sln --exclude-test-projects --output $(Build.ArtifactStagingDirectory)/bom

I now receive the follow exception when running with version 5.1.0:

Removed transitive dependency Microsoft.Extensions.Dependencyinjection.Abstractions from FluentValidation.DependencyInjectionExtensions
Found 359 packages

The exception came in the logs right after a test project (.net8.0)

Didn't have time to gather much info, but resolved it for now by downgrading again using the previous version:

- task: CmdLine@2
  displayName: 'Install CycloneDX CLI'
  inputs:
    script: |
      dotnet tool install --global --version 5.0.1 CycloneDX

A guess from the error message would be that it's related to 934

Thank you for reporting, great level of details. Bug should be fixed any moment.

I noticed this in your output:
Removed transitive dependency Microsoft.Extensions.Dependencyinjection.Abstractions from FluentValidation.DependencyInjectionExtensions, which is something I just implemented and didn't expect to see often.

Could you maybe check if your 5.0.1 SBOMs include the package Microsoft.Extensions.Dependencyinjection.Abstractions?

[alltho]

No problem :)

Checking the BOM xml output I see Microsoft.Extensions.Dependencyinjection.Abstractions referenced in versions:
@3.1.18
@8.0.0
@8.0.2
