Windows with its supporting libraries:

flowchart LR;
  external[Incoming requests] --> framework[.NET Framework App]
  framework --- libraries[[Business logic]]

but the core app is now set up to start migrating routes to: did below change?

flowchart LR;
  external[Incoming requests] --> core[ASP.NET Core App]
  core --- - --- libraries
  core -- YARP proxy --> framework[ \n\n.NET Framework App\n\n\n]
  framework --- libraries[[Business logic]]

In order to start moving over business logic that relies on HttpContext,

flowchart LR;
  external[Incoming requests] --> core[ASP.NET Core App]
  core -- Adapters --- libraries
  core -- YARP proxy --> framework[ \n\n.NET Framework App\n\n\n]
  framework --- libraries[[Business logic]]

Over time, the core app will start processing more of the routes served than the .NET Framework App:

flowchart LR;
  external[Incoming requests] --> core[ \n\nASP.NET Core App\n\n\n]
  core -- Adapters --- libraries
  core -- YARP proxy --> framework[.NET Framework App]
  framework --- libraries[[Business logic]]

Once the .NET Framework App is no longer needed, it may be removed:

flowchart LR;
  external[Incoming requests] --> core[ASP.NET Core App]
  core -- Adapters --- libraries[[Business logic]]

At this point, the application as a whole is running on the ASP.NET Core application stack,

flowchart LR;
  external[Incoming requests] --> core[ASP.NET Core App]
  core --- libraries[[Business logic]]
