DotNetOpenAuth 3.4 and Facebook as an identity provider/trusted provider

Dot开发者_运维知识库NetOpenAuth 3.4, Facebook

Does Facebook function as a provider (similar to Yahoo! or Google)? If so, does anyone have a pointer to example DotNetOpenAuth code?

Facebook supports OAuth 2.0, which a CTP of DotNetOpenAuth supports and includes a sample for that demonstrates figuring out who the user is.

Facebook does not currently function as a provider, only as a relying party/service provider. I need to use Facebook Connect to authenticate a Facebook user within my app.
