Mastering MediatR in C#: Building Scalable and Maintainable Applications: A Comprehensive Guide to Implementing the Mediator

Mastering MediatR in C#: Building Scalable and Maintainable Applications

In modern software development, writing clean, maintainable, and scalable applications is a crucial challenge. One of the most effective ways to achieve this is by reducing tight coupling between components and implementing a structured request-handling approach. Mastering MediatR in C#: Building Scalable and Maintainable Applications is a comprehensive guide to understanding and applying the Mediator Pattern using MediatR, a powerful library that enhances modularity in .NET applications.

This book takes a practical approach to integrating MediatR into real-world applications, helping developers streamline communication between components while improving maintainability and testability. It covers Command and Query Responsibility Segregation (CQRS), event-driven architectures, pipeline behaviors, dependency injection, and exception handling using MediatR.

Key Features:

Learn the Mediator Pattern and how MediatR helps achieve loose coupling in C# applications
Implement CQRS with MediatR to separate commands and queries for better scalability
Use notifications and domain events to manage event-driven architectures effectively
Integrate pipeline behaviors for logging, validation, and performance optimization
Set up dependency injection with MediatR in ASP.NET Core applications
Implement centralized error handling and logging strategies with MediatR
Master unit testing MediatR handlers using Moq and xUnit
Explore advanced techniques such as integrating MediatR with Entity Framework, database transactions, and distributed systems
Build a complete CRUD API using MediatR in a practical case study
This book is designed for C# developers, software architects, and ASP.NET Core professionals who want to enhance application structure and reduce complexity using MediatR. Whether you are new to MediatR or looking to deepen your knowledge, this guide provides a step-by-step learning experience that combines theory with hands-on examples.

By the end of this book, you will be able to apply MediatR efficiently in your projects, build highly scalable applications, and follow best practices for clean architecture in .NET development.
