Token Based Authentication in Asp.Net Core 2 - authentication

I've read some article on token based authentication in Asp.Net Core. I'm new to Asp.Net Core and Token based Authentication. Can anyone help me with that? Some code will be helpful for me. I'm using latest version of visual studio community 2017.

There is an excellent tutorial already written here
Also, IdentityServer4 have a lot of tutorials that show you how to configure identity server (to generate tokens) and how to secure your web api (token based authentication).

How can I have JWT authorisation in a standalone .NET Core ASP application?

I have been trying for weeks to implement JWT authorisation in my .NET Core web app and have found myself following a lot of guides that I don't think are relevant to my use case. These guides talk a lot about scopes etc, and I don't think I need that level of complexity for my use case.
A lot of the guides talk about using things like OpenIddict or Identity Server to setup and configure something that the user can authorise against, but in these settings it seems like a seperate project is required to house the identity provider, and then my new asp net core application has to somehow hook into that for use. I'm also trying to get things like refresh tokens to work so the user doesn't have to log in over and over again.
The "client side" of my app will be Xamarin (for mobile) and Angular (for web).
In a single web application (a single .net core application) how can I use .NET Core Identity with JWT or OAuth? What is the minimum level of configuration required to achieve this?
ThisSimple JWT project
This is not asp.net core .This is just asp.net mvc project but this really simple and basic one. by watching this code, you will be clear how to implement JWT. Thanks

asp.net core social authentication - Is this code designed for backend also, or only for client side?

I have been reading today about the auth implemented in asp.net core for google and facebook, and prototype-ed a lot. Something that's not clear to me at all, even after going through the MSDN docs. and several blogs: Is any support for backend API validation added in .net core or do I still need to call into the google auth library to validate the auth tokens received from the client.
Note: I am using asp.net core as Web API and I don't use the MVC/Razor part.
thanks for any detail added on this!

ASP.NET Core and Identity Server Authentication for SPA

I am starting a project with ASP.NET Core as an API Server and Angular 6 for the Frontend part but i am a bit lost with which exactly is the right way to authenticate users with the Identity Framework.
I read the documentation on http://docs.identityserver.io and also checked also the samples on github https://github.com/IdentityServer/IdentityServer4.Samples
Which is the correct way to authenticate users for my project ? I think i need the section "Using ASP.NET Core Identity" or "Adding User Authentication using OpenID Connect or "Adding Javascript Client" but i am not sure.
Which one best suits me?

Why Authentication type - individual user accounts for Web API in .NET Core is not available when we creating new Web APi service

Why it`s not possible to create Web API project with Individual User Accounts Authorization type?
UPDATE:
All version numbers are updated from v1.2 to v2.0.
Please find the ASP.NET Core Schedule and Roadmap:
Identity Application Services
A service layer will be added ASP.NET Core Identity and included in the project templates using Individual Authentication. This will allow authentication of users by way of JWT tokens such that Web APIs can be secured out of the box, and make it simpler to change authentication systems, e.g. from in-app Identity to Azure AD B2C, or 3rd-party solutions like Identity Server.
Daniel Roth from MS:
Support for individual user accounts with the Web API template in VS is not available yet. We are still looking at providing a supported on premise offering for token issuance in addition to providing integration with Azure AD B2C.
This statement can be found in the comment section under https://channel9.msdn.com/Events/dotnetConf/2016/Building-Secure-Web-APIs-with-ASPNET-Core
This is just disabled in core 1.1.please use core 2.0 to find all authentication.You can download core 2.0 from

How to implement Authentication and Authorization in Asp.Net 4.0?

Could any one suggest me the best sites to learn Authentication and Authorization Roles with some sample code ?Because am the beginner to security system in asp.net.
Tutorials here are very informative and in detail with sample code.
http://www.asp.net/web-forms/security (including videos)
https://web.archive.org/web/20211020202857/http://www.4guysfromrolla.com/articles/120705-1.aspx
There aren't any major changes in 4.0 in terms of authorization and authentication.
So any tutorial with 2.0+ should be fine.
