In this second edition, you will be guided through the journey of migrating an ASP.NET Framework application to ASP.NET Core microservices. You will know how to master the following steps: conduct an inventory, prepare the application, plan the migration, execute the migration, improve the deployment pipeline.
For the detailed hands-on migration, the book uses a streamlined business application, derived from a real-world application that underwent the migration process a few years ago. In this second edition, the application has evolved to include more features relevant to the latest advancements in ASP.NET Core, such as minimal web APIs, Razor Pages, REST documentation, and enhanced authentication. The book also delves into the nuances of upgrading between ASP.NET Core versions, managing breaking changes, and incorporating significant new features.
This guide includes practical examples from a complex system, detailed steps for migration, and an extensive list of resources and tools. I hope it provides all the information I initially struggled to find, helping you make informed decisions and focus on creating great software with ASP.NET Core.
