Roslyn Analyzers Integration Guide

Microsoft .NET compiler-integrated code analysis

Integrate Roslyn Analyzers with Vulnetix. Use the .NET SDK to run compiler-integrated analysis and produce SARIF output via MSBuild.

C# / .NETCLI toolSARIF

Install & scan

$ # Add the analyzer NuGet package
dotnet add package Microsoft.CodeAnalysis.NetAnalyzers
$ dotnet build /p:ErrorLog=roslyn.sarif,version=2

Run Roslyn Analyzers in CI

Scan on every push and upload the report as a workflow artifact:

- name: Build with analysis
  run: dotnet build /p:ErrorLog=roslyn.sarif,version=2
- name: Upload report
  uses: actions/upload-artifact@v6
  with:
    name: roslyn
    path: roslyn.sarif
    if-no-files-found: warn

Then one publish job hands every artifact in the run to Vulnetix, recorded under Roslyn Analyzers's own name and version. Written once per workflow, however many scanners you run:

publish:
  name: Publish to Vulnetix
  runs-on: ubuntu-latest
  needs: [scan]        # every scanner job, or its report is never published
  if: always()         # or one failing scanner suppresses all the others
  permissions:
    contents: read
    actions: read      # required to list the run's artifacts
  env:
    VULNETIX_ORG_ID: ${{ secrets.VULNETIX_ORG_ID }}
    VULNETIX_API_KEY: ${{ secrets.VULNETIX_API_KEY }}
  steps:
    - uses: actions/checkout@v5
    - name: Install Vulnetix CLI
      run: |
        curl -fsSL https://cli.vulnetix.com/install.sh | sh -s -- --install-dir "$HOME/.local/bin"
        echo "$HOME/.local/bin" >> "$GITHUB_PATH"
    - name: Publish scanner reports
      env:
        GITHUB_TOKEN: ${{ github.token }}
      run: vulnetix gha upload --org-id "$VULNETIX_ORG_ID" --json

After the run, vulnetix gha status reports what was actually recorded.

How Vulnetix compares: better together

Vulnetix does not replace Roslyn Analyzers. Keep running it. Vulnetix sits on top of Roslyn Analyzers (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.

Roslyn Analyzers is strongest at its core category and also carries features in Compilers, Linters & Code Quality, just as Vulnetix spans categories.

What Roslyn Analyzers does well

Where Vulnetix adds to it: Roslyn analyzers are .NET-only and compiler-bound; Vulnetix ingests their SARIF and unifies them with SCA, secrets, IaC, container and cloud findings across all languages, then adds EPSS/KEV exploit-intel, reachability and versioned VEX, orchestrating Roslyn rather than replacing its in-compiler checks.

No migration, no rip-and-replace. Roslyn Analyzers keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.

Centralise Roslyn Analyzers results in Vulnetix

Upload Roslyn Analyzers SARIF output to the Vulnetix platform to deduplicate findings, prioritise them with EPSS, CISA KEV and Coalition ESS exploit intelligence, and track remediation across every scanner in a single queue.
