I'm trying to create a simple Xamarin application that would need to use a local ADFS to identity the user. Indeed, I wrote an internal web application in ASP.NET Core but the client would like to have a light version as a mobile app, therefore, I need to authenticate the user the same way I do it for the web application: using ADFS 2019 + OAuth/OpenIdConnect.
However, I did some researches on Google and I find nothing talking about that specific case. Most articles concern Azure but I don't want to use Azure, I want to use a local ADFS.
Can anyone provide me with a link or some idea about the way to achieve this?
