Description
.NET 9 Microservices, Modular Monolith: DDD & Vertical Slice is a course on Modern Software Architecture using .NET 9 published by Udemy Online Academy. This is a comprehensive course that teaches modern software architecture using .NET 9. The course focuses on building scalable and maintainable applications by combining Domain-Driven Design (DDD), vertical slice architecture, and modular integration patterns. The course provides practical examples of designing microservices, structuring code to separate concerns, and applying best practices for high-quality enterprise applications. You will learn how to apply Domain-Driven Design (DDD) and vertical slice architecture to real business workflows—not cliché examples.
You’ll see how to translate business requirements into bounded fields, aggregations, value objects, and domain events, then implement them end-to-end with C#, ASP.NET Core, EF Core, gRPC, messaging, and Docker. Each feature is built as a vertical slice: from API contract and validation, through command controllers and domain logic, to persistence and testing. You should be familiar with C# fundamentals, have some experience with ASP.NET Core Web APIs, and know basic SQL (tables, relations, CRUD). It’s recommended that this isn’t your first C# project, however, I’ll guide you step-by-step from a bare-bones solution to a productive, production-style architecture.
What you will learn in .NET 9 Microservices, Modular Monolith: DDD & Vertical Slice:
- Design modular integrations and break them into microservices as needed
- Implement CQRS using MediatR and FluentValidation with Pipeline Behaviors
- Implement CQRS with FastEndpoints for high-performance, low-volume APIs
- Build minimal, flexible APIs using ASP.NET Core, with or without Carter
- Secure your APIs using role-based authentication with .NET Identity and JWT tokens
- Use gRPC for synchronous events and MassTransit for asynchronous microservice communication
- Manage domain events using SaveChangesInterceptor to create side effects
- Use GraphQL for efficient querying and filtering of a PostgreSQL database
- And…
