Migrating: ASP.NET Web APIs to ASP.NET Core

A step-by-step process to migrate ASP.NET Web APIs from .NET Framework to ASP.NET Core.

About This Course

.NET has been a staple in the development world for over twenty years. With the advent of .NET Core (now simply referred to as .NET), many existing .NET codebases are outdated and no longer supported. Numerous organizations find themselves stuck on older .NET Framework versions, and the need to transition to the modern ASP.NET Core has become essential. However, this migration can often feel daunting. In this course, Jonathan "J" Tower will guide you through the entire process of migrating ASP.NET Web APIs to ASP.NET Core. Drawing from his extensive experience assisting hundreds of companies with their migrations, J will equip you with the necessary skills to successfully update your Web API solutions to the latest ASP.NET Core framework.
