 # Azure Active Directory with ASP.NET Core
 
-## Azure AD V1 samples
+These tutorials and samples demonstrate authentication in ASP.NET Core using Microsoft identity platform and Azure Active Directory. For additional tutorials and samples using ASP.NET Core with Azure AD, see [Microsoft identity platform](/azure/active-directory/develop/).
 
-The following samples show how to integrate Azure AD V1, enabling users to sign-in with a work and school account:
-* [Integrating Azure AD Into an ASP.NET Core Web App](https://github.com/Azure-Samples/active-directory-dotnet-webapp-openidconnect-aspnetcore/tree/master) (archived and unsupported)
-* [Calling a ASP.NET Core Web API From a WPF Application Using Azure AD](https://github.com/Azure-Samples/active-directory-dotnet-native-aspnetcore)
-* [Calling a Web API in an ASP.NET Core Web Application Using Azure AD](https://azure.microsoft.com/documentation/samples/active-directory-dotnet-webapp-webapi-openidconnect-aspnetcore/)
+## Application Scenarios
 
-## Azure AD V2 samples
+* [Quickstart: Add sign-in with Microsoft to an ASP.NET Core web app](/azure/active-directory/develop/quickstart-v2-aspnet-core-webapp)
+* [Web app that signs in users](/azure/active-directory/develop/scenario-web-app-sign-user-overview?tabs=aspnetcore)
+* [Web app that calls web APIs](/azure/active-directory/develop/scenario-web-app-call-api-overview)
+* [Protected web API](/azure/active-directory/develop/scenario-protected-web-api-overview)
