Facebook C# SDK - Which DLL to use?

Question

I just downloaded the latest version of the Facebook C# SDK. I am migrating from the old Facebook Developer Toolkit.

I am using.Net 3.5 VS 2008. I will be using this SDK in Web and Console based apps. I noticed that the DLLs come in different flavors (Facebook, FacebookWeb, FacebookWebMvc). I am confused at to which one should I use for my Web and Console apps?

Also, what is the use for Facebook.Contracts.dll? Do I need to add it as a reference?

Any pointers?

UPDATE:

While trying to use the Facebook.Web.dll in my web app the following give me this error:"Precondition failed: .string.IsNullOrEmpty(settings:AppId)":

FacebookWebClient client = new FacebookWebClient(token);

The error goes away if I change it to:

FacebookClient client = new FacebookClient(token);

I am not sure why since there is VERY little documentation. So I guess I am going to stick to using the Facebook.dll for my Web app as well.

You need the Facebook assembly for any project; it is the core assembly and the others depend on it. Use just Facebook for your console application. Use Facebook + FacebookWeb for a Web Forms project. Use Facebook + FacebookWebMvc for an MVC project.
