问题
I have searched, read the FB developer docs.
MVC 4, I incorporated OpenId.
Now I want to include FB login as well, just as Stackoverflow and some other site have implemented it.
Do I create my own JS file with sample code from FB developer?
OR
Use a third party tools, which I am not aware of what to use. I did look at OAuthClient (DotNetOpenAuth-4.0.0.11165), it could not run, there was a server error and could not debug as the source file was missing.
回答1:
Facebook implements an older OAuth 2 spec than the latest DotNetOpenAuth beta does. To interop with Facebook, you should use the CTP of v3.5 of DotNetOpenAuth to avoid the 400 Bad Request error.

In the latest release of DotNetOpenAuth (4.0.0.12084) Login with Facebook works fine.
In order to make Sample solution build: install Code Contracts: http://msdn.microsoft.com/en-us/devlabs/dd491992.aspx
And to make example with Facebook login working you need to
- Create your own App on Facebook
- Specify you local website Url in the App settings (in "Select how your app integrates with Facebook" section)
- Update Web.config (OAuthClient project) file with your App ID and App Secret.
- in DotNetOpenAuth.ApplicationBlock.Facebook.FacebookGraph change type of Id property from int to long
- Run OAuthClient project. It should work.

Also read Release notes regarding OAuth 2.0 (http://www.dotnetopenauth.net/oauth/dotnetopenauth-4-0-released/) As far as I understand it's not yet stable, but I'm sill studying this. So far it works fine for me.
