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.
