How can I add custom claims ?

[AbdoDabbas]

I'm trying to follow this sample:
https://github.com/openiddict/openiddict-samples/tree/master/samples/PasswordFlow
But how to add custom claims to the returned response ?
Not only serialize them in the token, I want them to be returned clearly in the response of the token request.

You can read https://blogs.msdn.microsoft.com/webdev/2016/10/27/bearer-token-authentication-in-asp-net-core/ for an example of how to do that (in the Implementing the Connect/Token Endpoint section)

Thanks for replying, I'll read it.
Another question please, what's the difference between what you implemented in this sample, and the OpenIddict server library which contains Authentication provider ?

This one I mean.

As mentioned in the README, OpenIddict is based on ASOS. It implements all the validation routines for you and adds a bunch of security constraints so you only have to care about validating the user password and returning an identity. Everything else is managed for you by OpenIddict.
