Course Description

Overview

Learn how to build a RESTful API using ASP.NET Core Minimal API and Entity Framework and employ enterprise-level development practices and patterns. We will implement various support tools for data validation, logging, documentation, and security.

ASP.NET Core, based on .NET 6 (or the new .NET 7) runtime, is Microsoft's modern, cross-platform framework for building enterprise-ready web applications. This course will teach you everything you need to develop a Minimal API using .NET 6 (or .NET 7).

Why Learn ASP.NET Core / .NET 6 / .NET 7

Microsoft .NET is the platform that drives the business technology of many of the top corporations in the United States and many other countries. It is the predominant technology used to drive enterprise-scale business technology. Companies have chosen .NET for its proven scalability, reliability, and support. Only a few technologies have achieved this stability, maturity, and speed level. Creating a flexible yet stable technology is quite a feat, and that’s exactly what ASP.NET Core developers have achieved.

Why Learn to Build An API

The acronym API means Application Programming Interface. The ability to design and maintain an API is an important toolset for the modern web developer. It allows you to extend the accessibility of your software to external applications and other developers, leading to a more global software solution.

REST APIs have become a standard in the industry because they can serve essential functionality from any backend to any kind of frontend while catering to thousands of clients simultaneously. There is no time like now to skill up and start adding ASP.NET Core Web API to your skillset.

Build A Strong Foundation in .NET Programming:

  • Build a full data-driven REST Web API using cutting-edge technology

  • Test and Troubleshoot using Postman and Swagger

  • Create a database using Entity Framework Core

  • Generic Repository Pattern

  • Dependency Injection

  • Setup Logging using Serilog

  • Setup API documentation using SwaggerUI

  • Understand the REST design principles

  • Understand C# 11 and .NET Core Web Syntax

  • Setup Identity Core for User Authentication and Authorization

  • Understand user Authentication using JWT (JSON Web Tokens)

  • Implement Refresh Tokens Endpoint

  • Understand how to use Data Transfer Objects (DTOs) and AutoMapper

  • Integrate Fluent Validations

  • Manage Packages with NuGet Manager

  • API Caching and Request Rate Throttling

  • HTTP Request Filters

  • Understand .NET 6 / .NET 7 workflows, tools, and application development

PREREQUISITES

To take this course, you should have at least 3 months of experience programming in C#. If you need to strengthen your C# fundamentals, you can take my C# beginner course C# Console and Windows Forms Development with LINQ & ADO .NET

Content and Overview

To take this course, you must have some knowledge of Object Oriented Programming, if not C#. Even if you have little exposure to the .NET development stack, this course is beginner-friendly and full of development tips.

This is a huge course. Over 8 hours of premium content, but smartly broken up to highlight a set of related activities based on each module in the application that is being built, we will also look at troubleshooting and debugging errors as we go along, implementing best practices, writing efficient logic and understanding why developers do things the way they do. Your knowledge will grow, step by step, throughout the course, and you will be challenged to be the best you can be. This will put your newly learned skills into practical use and impress your boss and coworkers.

The course is complete with working files hosted on GitHub, including some files to make it easier for you to replicate the demonstrated code. You will be able to work alongside the author as you work through each lecture and will receive a verifiable certificate of completion upon finishing the course.
