I'm happy to announce that Microsoft Authentication Libraries (MSAL) for .NET and JavaScript are now Generally Available!  MSAL makes it easy for your application to sign in users and get access tokens to securely call protected APIs - from your own APIs to Microsoft Graph.  MSAL enables secure access to data for any Microsoft identity – from personal Microsoft accounts to work or school accounts provided by Azure Active Directory.
