MMCA.Common.Infrastructure |
EF Core multi-DB, repositories, UoW, caching, JWT, JWKS, outbox, message bus, SignalR |
MMCA.Common.API |
Base controllers, middleware, idempotency, error-to-HTTP mapping, JWKS endpoint |
MMCA.Common.Grpc |

MMCA.Common.UI.Web |
Blazor Web (Server + WASM) UI host helpers built on MMCA.Common.UI |
MMCA.Common.UI.Maui |
.NET MAUI UI head (the one MAUI-TFM package; built/packed by dedicated windows jobs, outside MMCA.Common.slnx, ADR-042) |
MMCA.Common.Aspire |
Service defaults, OpenTelemetry, health checks, Polly resilience |
MMCA.Common.Aspire.Hosting |
Aspire AppHost extensions: RabbitMQ broker, JWKS service discovery, gRPC project wiring |
MMCA.Common.Testing |
Integration test base, JWT generator, fixtures |
MMCA.Common.Testing.E2E |
Playwright E2E infrastructure: browser fixtures, Blazor nav helpers, Identity page objects |
MMCA.Common.Testing.UI |
bUnit component-test base, MudBlazor provider harness, interaction helpers |
MMCA.Common.Testing.Architecture |
IArchitectureMap + reusable NetArchTest rule library + abstract test bases (consumed by each repo's *.Architecture.Tests) |

New to the framework? Getting Started is the step-by-step guide for standing up a brand-new application: solution plumbing, a module vertical slice (domain → handler → endpoint → migration), the Aspire host, the architecture-fitness map, and a fully worked extraction of a module into its own microservice. It builds monolith-first, then shows the "extract later, without a rewrite" path.
- Architecture scorecard: the framework graded against a 34-category review rubric, with every category score, the weighted health index, top strengths, and the honest gaps.
- Architecture Decision Records: the accepted ADRs (001-022) explaining why the core cross-cutting patterns exist (outbox dual-dispatch, database-per-service, auth dual-fetch, soft-delete vs. erasure, gRPC extraction, and more). See
ADRs/README.mdfor the current count/range. - Contributor guide: package layout, layer dependency rules, and how to extend the framework.
