migrating-owin-cookie-auth

To migrate OWIN cookie authentication, replace the obsolete Microsoft.Owin.Security.Cookies middleware with ASP.NET Core's built-in AddAuthentication().AddCookie() configuration. This process identifies legacy package usage and guides reference updates to complete the authentication upgrade.

OWIN cookie authentication relies on the legacy Microsoft.Owin.Security.Cookies package, whereas ASP.NET Core uses built-in middleware configured via AddAuthentication().AddCookie(). Migrating replaces obsolete packages with modern ASP.NET Core equivalents.

Yes, updating package references is required when moving from OWIN to ASP.NET Core authentication. You must replace obsolete OWIN packages with their ASP.NET Core equivalents to ensure the new AddCookie() middleware functions correctly.

Yes, you can automate the upgrade from legacy OWIN cookie middleware to ASP.NET Core. This Skill automates identifying obsolete OWIN usage and provides guided steps to replace middleware and update references for your .NET Core applications.

The migration targets .NET Core applications upgrading their authentication system. It is specifically designed for cookie authentication scenarios, guiding the replacement of OWIN middleware but may not cover other authentication types or complex custom OWIN implementations.
