Any update on this? Thanks.

@yohanb : I don't think that would be possible. Microsoft.AspNetCore.Authentication.JwtBearer (which is one of our dependencies) for instance does not have a target platform for netstandard2.1 ...

[yohanb]

@jmprieur maybe it would be possible to extract most of the functionality into a separate package that is netstandard compatible. For example, implementing ITokenAcquisition or using MicrosoftIdentityOptions in a library project would make sense as opposed to an aspnetcore project.

Thanks @yohanb :as we are making more features available in .NET framework, we'll think of your suggestion.
Which public API would you like to see in the netstandard project?

[jennyf19]

blocked as MSAL.NET does not support netstandard2.1

@jennyf19 Latest version of Microsoft.Identity.Client does target netstandard2.1

[jennyf19]

@stephenjust We recently split the Ms.Id.Web package into smaller nuget packages for the tokenCache and certificate loading both of which support netstandard2.0.

Would that give you the APIs you are looking for?

Yes, this is helpful, thanks!
