dotnet-api-surface-validation
dotnet-api-surface-validation
Tools and workflows for validating and tracking the public API surface of .NET libraries. Covers three complementary approaches: PublicApiAnalyzers for text-file tracking of shipped/unshipped APIs with Roslyn diagnostics, the Verify snapshot pattern for reflection-based API surface snapshot testing, and ApiCompat CI enforcement for gating pull requests on API surface changes.
Version assumptions: .NET 8.0+ baseline. PublicApiAnalyzers 3.3+ (ships with Microsoft.CodeAnalysis.Analyzers or standalone Microsoft.CodeAnalysis.PublicApiAnalyzers). ApiCompat tooling included in .NET 8+ SDK.
Out of scope: Binary vs source compatibility rules, type forwarders, SemVer impact -- see [skill:dotnet-library-api-compat]. NuGet packaging, EnablePackageValidation basics, and suppression file mechanics -- see [skill:dotnet-nuget-authoring] and [skill:dotnet-multi-targeting]. Verify library fundamentals (setup, scrubbing, converters) -- see [skill:dotnet-snapshot-testing]. General Roslyn analyzer configuration (EditorConfig, severity levels) -- see [skill:dotnet-roslyn-analyzers]. HTTP API versioning -- see [skill:dotnet-api-versioning].
Cross-references: [skill:dotnet-library-api-compat] for binary/source compatibility rules, [skill:dotnet-nuget-authoring] for EnablePackageValidation and NuGet SemVer, [skill:dotnet-multi-targeting] for multi-TFM ApiCompat tool mechanics, [skill:dotnet-snapshot-testing] for Verify fundamentals, [skill:dotnet-roslyn-analyzers] for general analyzer configuration, [skill:dotnet-api-versioning] for HTTP API versioning.
PublicApiAnalyzers
PublicApiAnalyzers tracks every public API member in text files committed to source control. The analyzer enforces that new APIs go through an explicit "unshipped" phase before being marked "shipped," preventing accidental public API exposure and undocumented surface area changes.
Setup
Install the analyzer package:
