I am going to create an web app using Dot Net Core. In future, i will also create mobile application for the same application. Now, i am in thinking the architecture of the project. I want to use WEB API core using Asp.net Identity Core. Also, i will consume WEB API in MVC Core application. But the question i have in mind that how i can handle ASP.net identity with MVC and WEB API? Do i need to include in MVC as well or only in WEB API?
I tried to think hard but still confuse. Need suggestions.
You can use token based authentication .
In a resource owner flow scenario , your client app( mvc application/native application) will consume your web api by providing user's credential , web api will validate the credential(using ASP.NET Core Identity) in database , If the username and password are correct then a JWT authentication token and the user details are returned. Your client app could validate the token and sign in user :

In addition, IdentityServer4 is a good choice when you want to roll your own full-fledged OpenID Connect authorization server that can handle complex use cases like federation and single sign-on.
So your question is maybe a bit open-ended for Stackoverflow and you don't really show what you have tried so far.
I will try to answer though. First you just need to start out with a template for your project. Start an MVC project in which you can easily have API endpoints as well. I would suggest splitting those in two projects for clarity - but if it is just a small personal project then you probably are fine having them in the same project. Microsoft have a pretty good resource on MVC:

For the Identity part. You would need some kind of authority for it to work. I suggest you take a look at IdentityServer4. Which offers an excellent walk-through of how to set it up and how to integrate it with Asp.NET Core Identity:

I am building an AngularJS MVC application, I need some guidance in terms of authentication. I am thinking of building the Authentication using the MVC authentication pipeline. AngularJS code will reside in the MVC application and the root SPA view would be a Razor cshtml. Here is my scenario -
Login page will call a Authenticate API that would return a token
AngularJS has the logic to get the bearer and pass to each of the API requests
There will be multiple ASP.NET WebAPI projects that will be hosted as subdomains.
I also need to call complex dynamic razor templates, this would need the authentication for the MVC controller that will return the razor views. Since MVC follows cookie based authentication, the token gives a 401 status code. How would this work wherein the authentication is shared between MVC and WEB API apps.
I think you would need to get your token from the API project, not the MVC in order to be able to securely call the API.
If you want to share identities across both the API and MVC projects, have them use the same database.
When getting the token from the API, you can get the identity details of the current user from your MVC application. At least, that is how I have done it in the past.
I blogged something along these lines here: http://blogs.msdn.com/b/martinkearn/archive/2015/03/25/securing-and-working-securely-with-web-api.aspx however this does not cover the step of using the creds from your MVC login and passing that to the API to get the token.
Hope that helps.
If I have an MVC application that has an authenticated user, and either from client-side JavaScript, or from an MVC controller, I wish to call a Web API that is in a different project to the MVC application, but use the same user credentials.
How would I go about this?
I am using the latest in VS2013 - MVC 5 with Web API 2. Currently to authenticate I am using forms auth.
Please refer the following link to solve your problem
Works fine for me
Web api authentication and MVC 4
i upgrade my application from mvc4 to mvc5. i am using Entity Framework code first approach in my application. i am confuse about OWIN and Katana. how i implement these concept in my web mvc5 application. please guide me.
Thank you
ASP.NET MVC was not designed to work with OWIN. It's the ASP.NET Web API and SignalR that were built for OWIN and provide specific host. So you cannot implement those concepts in an ASP.NET MVC application.
So far the only MVC framweworks I have found that support OWIN are NancyFx or FubuMVC.
I am confused about how to build the custom oauth client in asp.net mvc 5.
In mvc 4 it was a simple operation. Implementing custom class from IAuthenticationClient. And then in AuthConfig.cs call the function OAuthWebSecurity.RegisterClient. But how it can be done in mvc 5?
Mvc5 authentication is built on Katana (OWIN components by Microsoft). Check following article for detailed overview of Authentication changes in MVC5.
