ServiceFoundry.ContractEvolution

Versioned contract evolution for .NET — register API or message contract versions, resolve multi-hop upgrade paths, assess compatibility, and catch unsafe maps before compile time with the included Roslyn analyzer.

Packages

Package Purpose
ServiceFoundry.ContractEvolution Core registry, engine, and upgrade DSL
ServiceFoundry.ContractEvolution.AspNetCore Request version reading and body upgrade middleware
ServiceFoundry.ContractEvolution.Testing Assertion helpers for unit and integration tests
ServiceFoundry.ContractEvolution.Reporting Text and JSON report writers
ServiceFoundry.ContractEvolution.Analyzers Roslyn analyzer (SFCE001)

Install

dotnet add package ServiceFoundry.ContractEvolution
dotnet add package ServiceFoundry.ContractEvolution.Analyzers  # analyzer, development-only

Getting started

// 1. Register contract versions and their upgrade maps
builder.Services.AddContractEvolution(evolution =>
{
    evolution.ForContract<OrderContract>(contract =>
    {
        contract.Version<OrderV1>("v1");
        contract.Latest<OrderV2>("v2");

        contract.Map<OrderV1, OrderV2>("v1", "v2", map =>
        {
            // Same-named properties are copied automatically.
            // Provide explicit rules for additions, renames, and computed values.
            map.Default(o => o.Currency, "USD");
        });
    });
});

// 2. Upgrade at runtime
var result = engine.Upgrade<OrderContract, OrderV2>(incomingPayload, sourceVersion: "v1");
var upgraded = result.Value;  // OrderV2 with Currency = "USD"

The MissingTargetBindingAnalyzer (SFCE001) will warn at build time if Currency above were omitted from the map entirely.

Runtime behaviour when no path exists

If ResolvePlan or Upgrade is called for a source/target pair with no registered upgrade path, a ContractEvolutionValidationException is thrown containing the list of diagnostics. If the registration itself is invalid (e.g. a cycle or an ambiguous path), the exception is thrown at Build() time, before the app starts.

Features

  • Typed DSL: Version, Latest, Map, Copy, Rename, Default, Compute
  • Multi-hop BFS path resolution
  • Compatibility assessment: Compatible, Upgradeable, Breaking
  • Graph validation at Build() time (cycles, ambiguous paths, missing bindings)
  • Text and JSON report writers via ContractEvolution.Reporting
  • SFCE001 Roslyn analyzer — warns on unmapped target properties at compile time
  • ASP.NET Core request-body upgrade hook

See samples/ContractEvolution/README.md for additional examples.
