Migration tools for ASP.NET to ASP.NET Core

 The incremental ASP.NET migration tooling extension can be installed from the Visual Studio Marketplace

The System.Web adapters ship in four packages:

• Microsoft.AspNetCore.SystemWebAdapters – The core adapters package which includes adapters for common System.Web APIs, allowing them to be used from .NET Standard targeted projects.
• Microsoft.AspNetCore.SystemWebAdapters.FrameworkServices – Adds new functionality to ASP.NET apps for incremental migration scenarios. This includes exposing endpoints for sharing session or authentication state with paired ASP.NET Core apps.
• Microsoft.AspNetCore.SystemWebAdapters.CoreServices – The corresponding package for ASP.NET Core apps to take advantage of new functionality for sharing session or authentication state with an ASP.NET app during incremental migration.
• Microsoft.AspNetCore.SystemWebAdapters.Abstractions – A collection of shared abstractions for the Core and Framework System.Web adapter packages

This page now has a new button Endpoints explorer that will visualize the endpoints, or routes, which have been migrated and those which have not. When you click on that button, the Endpoints explorer view will be opened. See the following image.
