6 years agoThe .NET SDK isn't officially supported for Xamarin, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
For reference though, if you need to implement the OAuth app authorization flow, you can find the documentation here. And here's where it's implemented in the .NET SDK for reference.

Ok, thank. I will quickly try it. I was trying some code, and I have been able to see the authorization code in the device browser, the code that must be used in the post request to get the access token. My problem in this way is that i don't know how to retrieve this code displayed in the url bar and put it in the post request. If there is a method that can extract this code from the redirectde url in C#, i will try it also. Thank for the replay.

Yes, when using the OAuth 2 app authorization "code" flow with a redirect URI, the authorization code is returned in a URL parameter with the name "code" on the redirect URI. You would need to retrieve that parameter value, though exactly how you do so will depend on whatever web framework you're using. Or, if you're not using a redirect URI, you can have the user manually copy/paste the code into your app.

Thank Greg K for the interest. I'm trying Webview and the device native Browser (that I open with "await Browser.OpenAsync(authorizeUri, BrowserLaunchMode.SystemPreferred)" where "authorizeUri" is the authorization uri). But I alway failed. In the POST request, I must also put the redirect uri. Then, I would like to be sure about the "REDIRECT URI". I've read its definition a lot, but I am not very sure how to set its. The one that I'm using is valid ? I don't know. It is "https://dev-5-6ei48x.auth0.com/login/callback". What are the steps and rules to get this redirect url (not "WHERE" to put it but "HOW" to get it).
