Upgrading a legacy ASP.NET 4.x application to ASP.NET Core does not require an all-at-once rewrite. An incremental strangler-fig pattern ensures business continuity.

Start by decoupling the database access layer from System.Web dependencies. Move shared business rules into .NET Standard libraries, and begin routing new API endpoints to an ASP.NET Core service behind an API gateway.
