Building Modular Monoliths with Modern .NET

As applications grow, traditional monoliths become difficult to maintain, while microservices introduce high operational complexity. Transitioning to a modular monolith offers the perfect middle ground, allowing you to build highly organized, scalable systems without the overhead of distributed infrastructure. This text-based course guides you through the process of designing and implementing modular monoliths using modern .NET. You will learn how to logically separate your application's domain logic, manage communication between modules, and structure your codebase for maximum maintainability and future scalability. What you'll learn: Understand the core architectural principles of modular monoliths and how they compare to traditional monoliths and microservices; Define clear bounded contexts and domain modules to ensure high cohesion and low coupling; Implement asynchronous and synchronous communication between modules using clean interfaces; Structure your .NET solution using modern dependency injection, minimal APIs, and clean architecture patterns; Apply database separation strategies, including schema-per-module, to keep data storage isolated; Write robust integration tests to verify module boundaries and overall system behavior. The course begins with essential architectural definitions and foundational concepts before moving into step-by-step code structures and design patterns. You will progress from initial solution setup to module isolation and communication strategies. This course is designed for backend developers and aspiring software architects who are familiar with basic C# and .NET concepts and want to master modern software architecture. No prior experience with system design or microservices is required. Start reading today to build cleaner, more maintainable .NET applications.
