SeamGuard

SeamGuard is a C# Roslyn analyzer for enforcing JSON-defined architectural boundaries during .NET builds.

SeamGuard runs as an installed analyzer or as a .NET tool that injects the analyzer for one build. Both modes use the same configuration format.

What SeamGuard checks

Behavioral types declared by a project, filtered by kind and visibility.
Direct type references and constructor dependencies.
Direct project and NuGet package references.
InternalsVisibleTo friend assemblies.
Mock providers and mocked types in test code.
Layered project and type rules with namespace and kind filters.

Quick start

dotnet add package SeamGuard.Analyzer

Create .seamguard/config.json beside the solution or in the project directory or one of its ancestors.

{
  "version": 1,
  "projects": {
    "General.Core": {
      "projectReferences": {
        "deny": ["General.Data"]
      },
      "rules": [
        {
          "target": "General.Core.Services.**",
          "constructorDependencies": {
            "allow": ["System.**", "General.Contracts.**"],
            "deny": ["General.Data.**"]
          }
        }
      ]
    }
  }
}

dotnet build reports forbidden crossings as SGA diagnostics.

The tool runs SeamGuard without adding an analyzer reference to the target repository.

dotnet tool install --global SeamGuard.Tool
dotnet seam build path\to\Project.sln --config path\to\.seamguard\config.json -- -c Release
