Custom oAuth client in ASP.NET MVC 5 - oauth-2.0

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.

Can I use asp.net identity with MVC 5 where back-end is web API?

I have a web API which is written in java and on front end I am creating an Admin panel so to protect our restricted page I could use form based authentication however I heard that form based authentication has been deprecated(https://softwareengineering.stackexchange.com/questions/284380/is-formsauthentication-obsolete) from MVC 5 onward so Is there any alternative that I can use in this scenario?
You can install web api framework in mvc project with nuget. And install Microsoft.AspNet.Identity, Microsoft.AspNet.Identity.EntityFramework,
Microsoft.AspNet.Identity.Owin. So you can use identity in MVC framework.

MVC 5 and WebApi2 using OWIN OAuth

I am creating an application that will use MVC 5 to serve the initial layout, views, scripts, etc. and then I am using WebApi2 to serve data to the UI.
I want to use the OWIN OAuth bits for Authentication on the WebApi.
The WebApi lives in a DLL and the MVC 5 app is a Web Application.
I have referenced this article for the OAuth WebApi bits.
How do I setup the WebApi to run in the MVC 5 application and use the OWIN Startup class?
Or is this not possible?
I recommend you to check the VS 2013 Web API template (Web API and MVC core dependency) but with individual accounts checked as this image, I believe you are missing adding those both lines in class WebApiConfig.cs:
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
You need to suppress the default authentication (Forms Auth) then add the bearer authentication only for Web API.

How to Implement OWIN and Katana in MVC 5Application

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.

OAuth security for calling Controllers using Attrubutes?

Is there anyway, that you can lets say use OAuth in MVC and enable acces to a controller using Attributes like in validation process.
Lets say i have
public class myownController
{
[LoginRequired]
public ActionResult Index(){
//this can be accesed only of the user is logged in.
}
}
If you're using ASP.Net MVC 4 this should be built in using the default AuthorizeAttribute. If not I'd recommend manually integrating the standard Forms Authentication mechanisms with your chosen OAuth provider. Take a look at ASP.NET MVC Authentication - Customizing Authentication and Authorization The Right Way
Since you are using ASP.Net MVC 4, I'd highly recommend reading SimpleMembership, Membership Providers, Universal Providers and the new ASP.NET 4.5 Web Forms and ASP.NET MVC 4 templates. There are significant changes available in MVC 4 that make the entire Membership and OAuth really easy.
