 It leverages the ASP.NET Core OpenID Connect middleware and Microsoft Authentication Library for .NET (MSAL.NET). The complexities of the library's integration with the ASP.NET Core dependency Injection patterns is encapsultated into the `Microsoft.Identity.Web` library project, which is a part of this tutorial.
