Specifically, the ubiquity of   System.Web.HttpContext.Current . In the legacy ASP.NET era,  HttpContext.Current  was the "God Object." It allowed any method, no matter how deep in the call stack—static utility classes, logging extensions, business logic—to reach out and grab the Request, Response, Session, or User Identity without passing parameters. In ASP.NET Core, it does not exist. This post details why the architecture changed, how to implement the modern Dependency Injection (DI) solution, and provides a rigorous "shim" strategy for legacy codebases where refactoring every constructor immediately is impossible. The Root Cause: Why it was Removed System.Web.HttpContext.Current  relied heavily on  System.Runtime.Remoting.Messaging.CallContext  and was tightly coupled to IIS (Internet Information S...
