Cause (Maintainer-confirmed cause): Maintainer-tracked regression: Central Package Management migration moved PrivateAssets=All to Directory.Packages.props, which NuGet ignores at nuspec generation.
Fix status: released_fix (fixed in 2.9.1)
Workaround (not a fix): Downgrade to 2.8.0.
Misleading approaches:
- Debugging your own repo's git/SourceLink configuration — the targets come from the OpenAI package.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/openai/openai-dotnet/issues/991 (github_issue, 2026-02, maintainer_confirmed_cause): 2.9.0 leaked Microsoft.SourceLink.GitHub 10.0.102 as runtime dependency via CPM migration (PR #890); consumers get 'Source control information is not available'; fixed by PR #994; workaround downgrade to 2.8.0.
- https://raw.githubusercontent.com/openai/openai-dotnet/main/CHANGELOG.md (changelog, 2026-03-02, released_fix): 2.9.1 changelog: fixed Microsoft.SourceLink.GitHub inadvertently included as runtime dependency causing 'Source control information is not available' build failures.

Problem details
- Observed symptom
- Build breaks (or warns) after bumping OpenAI to 2.9.0, error mentions SourceLink though project doesn't use it.
- Context
- Product: OpenAI .NET SDK (OpenAI NuGet package) Component: package dependencies (Microsoft.SourceLink.GitHub) Operation: dotnet build of a project referencing OpenAI 2.9.0 Affected versions: 2.9.0 (regression from 2.8.0) Environment: unknown Packages: OpenAI 2.9.0 Trigger: OpenAI 2.9.0 declared Microsoft.SourceLink.GitHub (and Common, Build.Tasks.Git) as regular dependencies, injecting SourceLink MSBuild targets into consumers.

Proposed fix: [OpenAI .NET 2.9.0] Consumer builds fail 'Source control information is not available - the generated source link is empty' (SourceLink leaked as runtime dependency)
Recommended action: Upgrade to OpenAI 2.9.1+ (SourceLink is build-only again) or pin 2.8.0.
Fix: Upgrade OpenAI NuGet to 2.9.1+ [evidence: released_fix]
Applies when: Projects on OpenAI 2.9.0
Steps:
1. dotnet add package OpenAI --version 2.9.1 (or later)
2. Clean and rebuild
Expected: SourceLink targets no longer injected
Evidence basis (self-declared by the contributing chat client): untested.
