I have using VS2015 to create an ASP.net Web Application with Empty template. After this, i am using Nuget to install UmbracoCms into my Asp.net project. I compile and run and manage to login into my back office.

I have manual create the 'Models' and 'Controllers' into my project and create all other cs file for my MVC.

Now, i need to use OpenID connect to external IdentityServer to validate login for consume external API services. I don't need to sync member/user from IdentityServer. Just need to check how can i start to put in my OpenID code and any reference guide for this in Umbraco ?

* I already got "ClientId", "ClientSecret", "AccessTokenEndpoint" and "AutohrizedEndPoint" from IdentityServer.

Thanks in advance.
