MSAL or ADAL library for use with Azure AD B2C and Xamarin

Question

As of October 2016, is it still the case that the Microsoft Authentication Library (MSAL - NuGet package: Microsoft.Identity.Client) is the correct/only library to

Answer 1

It is not possible. As you say, ADAL is generally available and supported - however, it is designed to only work against Azure AD "classic" (e.g. - NOT B2C) and ADFS "3.0" onward. There are important protocol and feature differences that make the ADAL OM and protocol capabilities incompatible with B2C. MSAL represents the new generation of Microsoft's authentication libraries, designed to work with Azure AD v2 endpoints, Microsoft Accounts (MSA) and Azure AD B2C. It is still in preview, but it is under active development - if you observe its repo at https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/, you'll see various branches being worked on. If you want to experiment with B2C and Xamarin, that's the library to use. At this time we cannot share an ETA for when it will be generally available. thanks V.
