Does the Facebook C# SDK have any OAuth 2.0 authentication baked into the library?

I'm wanting to create a website and have users log in to my site, etc. BUT I don't want to have to get them to create a username/password, etc. So I'll ask them to authenticate with their Facebook account (assuming they have one).

So I've had a look at the Authentication docs on Facebook and I'm wondering if

• Does the Facebook C# SDK have any libraries/code that does a lot of this heavy lifting?
• If so, any links to sample code I can see? I've tried having a look at the Samples folder in the source code .. but there's nothing that suggests this.
