Issue: #760

Thanks for your contribution - just some minor code style comments.

Have you verified that these changes work as expected in a real application with the Autodesk v2 API?

[kevinchalet]

Note: you forgot to update the address of the userinfo endpoint to use the v2 userinfo API. See https://github.com/aspnet-contrib/AspNet.Security.OAuth.Providers/pull/788/files.

Isn't it done as per the following screenshot?

@EMostafaAli I don't see this change in this PR:

Are you sure you pushed the changes to the correct branch?

(also, you'll likely need to update the claim mapping in the options class)

[EMostafaAli]

My bad, I was looking at different code. I will try to make the changes quickly.

[EMostafaAli]

@kevinchalet , updated the user info endpoint

[kevinchalet]

@EMostafaAli it looks like you didn't fix the points mentioned by @martincostello. We'll also need you to fix #764 (comment) before being able to merge this PR.

[EMostafaAli]

@kevinchalet, I hope this new commit addresses your comments.

[martincostello]

The tests are failing.

@martincostello, Done

[kevinchalet]

Thanks for your PR!

I'll leave @martincostello decide what to do next, as this PR is technically a breaking behavior change, given the claims are changing 😃

[kevinchalet]

Technically, the standard way of computing the Authorization: Basic [...] header requires formURL-encoding the client identifier and client secret individually before computing their base64 representation. That said, I see in the Autodesk docs that they don't mention formURL-encoding so their implementation is probably not 100% compliant. Let's keep it this way.
