 Depending on the type of application you're building, and its underlying platform, you can choose to use MSAL.NET, [Microsoft Identity Web](https://github.com/AzureAD/microsoft-identity-web), or both.
 
 Microsoft Identity Web is a set of ASP.NET Core libraries that simplifies adding authentication and authorization support to web apps and web APIs integrating with the Microsoft identity platform. It provides a single-surface API convenience layer that ties together ASP.NET Core, its authentication middleware, and the Microsoft Authentication Library (MSAL) for .NET.
