Authentication with Google or Facebook - asp.net

I'm using ASP.NET MVC and I want to authenticate users with their Google or Facebook account

Check the Url http://codechallenger.blogspot.com/2011/03/autenticacion-de-usuarios-contra.html
The post is in spanish

I believe both of those providers support OpenID. While some people out there bash it, I know other sites that have used it with great success.
I would start by finding a good OpenID provider for .NET and go from there.

I would recommend your first step would be to look into authenticating using OpenID (and integrating with WIF) as both Google and Facebook provide OpenID

For this you use Twitter's OAuth authentication framework. It's used so that users don't have to directly enter their user + password into your site. (I assume you know how the front-end to that works already.)
You can use this little example to use OAuth from .NET - it is built for ASP.NET. (The demo the guy provides is My Tweeple.)
Twitter actually includes instructions for using OAuth to make a Facebook Connect-style system.

How to integrate open ID Login

I want to integrate Open ID, Google and Yahoo login in my site, So please anyone can tell me the process of integration in ASP.NET.
Google and Yahoo support OpenID, so you just need to OpenID enable your website.
This is a great article which tells you step by step of what you need to do. You will still need an OpenID library for .NET in order to do that.
I have actually written a blog post on How to add OpenID authentication to your site using Janrain Engage that might help you along.
It's written with an ASP.NET MVC 3 application in mind, but there's nothing in there you cannot use in an ASP.NET app.
