-> [!NOTE]
-> To use session state with System.Web adapters, endpoints must explicitly opt-in via metadata implementing `ISessionMetadata`.

-In order to support <xref:System.Web.HttpContext.Session>, endpoints must opt-into it via metadata implementing `ISessionMetadata`.

-**Recommendation**: To enable this on all MVC endpoints, there is an extension method that can be used as follows:
-
-```cs
-app.MapDefaultControllerRoute()
-    .RequireSystemWebAdapterSession();
-```
-
-This also requires some implementation of a session store. For details of options here, see the sections below on different session approaches.

 Choose this approach when you're performing a complete migration and can rewrite session-related code to use ASP.NET Core's native session implementation.
