.NET 8 Web Api - Clean Architecture Full Guide from Udemy

This course is designed for developers who want to deepen their understanding of .NET architecture and data management. The course covers a range of topics, including the CQRS architectural pattern, EntityFrameworkCore, Eager Loading, Repository Patterns, Database Migrations, MSSQL Database, FluentValidation, AutoMapper, MediatR, and Redis Cache.

You will learn how to implement these tools and techniques in your .NET applications to improve performance, scalability, and maintainability. We will explore MediatR Request and RequestHandler, MediatR Request Pipeline Behaviours, and Global Exception Handling Middleware, and discuss best practices for using IServiceCollection Extensions, Custom Exceptions, and IOptions for configurations.

In addition, we will dive into the importance of DTOs - Data Transfer Objects, and how they can be used to separate the domain data model from outgoing models in .NET applications. We will also cover SwaggerUI Request Duration, a feature that displays the time it takes to complete requests in SwaggerUI, and how it can be used to monitor and optimize application performance.

Throughout the course, you will work on hands-on project and assignments that will help you apply what you have learned to real-world scenarios. By the end of the course, you will have a comprehensive understanding of advanced .NET architecture and data management, and the skills and knowledge to implement these tools and techniques in your own applications.
