Start writing applications TODAY with the new Microsoft Authentication SDKs
MSAL is an SDK that makes it easy for you to obtain the tokens required to access web API protected by Microsoft identities, that is to say by the v2 protocol endpoint of Azure AD (work and school accounts or Personal Microsoft Accounts), Azure AD B2C, or the new ASP.NET Core Identity. Examples of web API include Microsoft Cloud API, such as the Microsoft Graph, or any other 3rd party API (including your own) configured to accept tokens issued by Microsoft identities.
