MediatR curriculum: 4 modules over 4 days
Module 1 : MediatR Fundamentals: Handlers and Dependency Injection (NuGet, Microsoft.Extensions DI)
Quick installation of MediatR via NuGet in an existing ASP.NET Core project, creation of first handlers for requests and commands with message validation, configuration of dependency injection for total decoupling, practical exercises on a real e-commerce case where you implement product queries, asynchronous notification sending, and code review to identify common pitfalls, producing a functional prototype ready for the enterprise.
Module 2 : MediatR Pipelines: Custom Behaviors (Logging, FluentValidation, Caching)
Deep dive into MediatR pipelines to intercept requests, development of custom behaviors for logging with Serilog, automatic payload validation via FluentValidation, intelligent caching with IMemoryCache, application to a complex business scenario like user management, live testing of nested behavior chains, flow optimization to reduce latency by 40%, and delivery of a reusable module certifying your professional skills.
Module 3 : CQRS with MediatR: EF Core and Dapper Integration (Separate Queries, Aggregates)
Full CQRS implementation driven by MediatR, strict separation of read handlers with Dapper for ultra-fast queries and write handlers with EF Core for transactional commands, domain-driven aggregate modeling, event handling via INotification, exercises on a simulated banking project including concurrency and idempotency, performance profiling to validate scalability, and production of a decoupled backend ready for the enterprise team.
Module 4 : MediatR Optimization: Advanced Testing and Deployment (xUnit, BenchmarkDotNet, Azure)
Exhaustive unit tests for MediatR handlers with xUnit and Moq for 90% coverage, performance benchmarks via BenchmarkDotNet to identify bottlenecks, integration of MediatR into Kubernetes for zero-downtime deployment, monitoring with Application Insights, resolution of real production failure cases like memory leaks, finalization of the red thread project with GitHub Actions CI/CD, and delivery of a complete dossier to certify your expertise in professional training.
