-# Authentication samples for ASP.NET Core
-
-By [Rick Anderson](https://twitter.com/RickAndMSFT)
-
-The [ASP.NET Core repository](https://github.com/dotnet/aspnetcore) contains the following authentication samples (`main` branch):
-
-* [Claims transformation](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/ClaimsTransformation)
-* [Cookie authentication](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/Cookies)
-* [Custom authorization failure response](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/CustomAuthorizationFailureResponse)
-* [Custom policy provider - IAuthorizationPolicyProvider](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/CustomPolicyProvider)
-* [Dynamic authentication schemes and options](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/DynamicSchemes)
-* [External claims](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/Identity.ExternalClaims)
-* [Selecting between cookie and another authentication scheme based on the request](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/PathSchemeSelection)
-* [Restricts access to static files](https://github.com/dotnet/aspnetcore/tree/main/src/Security/samples/StaticFilesAuth)
-
-## Obtain and run the samples
-
-The sample links provided in this article provide samples for the upcoming release of ASP.NET Core. To obtain a sample for the current release or a prior release, perform the following steps:
-
-* Select the release branch of the [ASP.NET Core repository](https://github.com/dotnet/aspnetcore). For example, the `release/5.0` branch contains the samples for the ASP.NET Core 5.0 release.
-* Clone or download the ASP.NET Core repository.
-* On your local system, verify installation of the [.NET Core SDK](https://dotnet.microsoft.com/download/dotnet-core) version matching the clone of the ASP.NET Core repository.
-* Navigate to a sample in `aspnetcore/src/Security/samples` folder and run the sample with the [`dotnet run` command](/dotnet/core/tools/dotnet-run).
