I guess MonoDevelop should not provide completion for extension methods when System.Core is not referenced. MD should also reference System.Core by default in new 3.5+ projects. Please file bugs. Arguably gmcs should give a better error message too, so please file a separate bug against gmcs for that.

If you have extension methods in one assembly and then use those extension methods in another, if you do not reference System.Core then the compiler can't find those methods. I think the big problem is it's hard to diagnose. MonoDevelop will happily offer code-completion for those extension methods. However, when you compile, it fails. Unfortunately the error info doesn't give you any sort of clue that it's a missing System.Core reference and *NOT* a missing method. VS.NET will happily offer code-completion *and* compile. Example of an error message: Messenger.cs(34,34): Error CS1061: Type `Dimebrain.TweetSharp.Fluent.IFluentTwitter' does not contain a definition for `AuthenticateAs' and no extension method `AuthenticateAs' of type `Dimebrain.TweetSharp.Fluent.IFluentTwitter' could be found (are you missing a using directive or an assembly reference?) (CS1061) (Infrastructure) The last part - "are you missing a using directive [...]" - is misleading because that makes me think I need to add a reference to TweetSharp. But what it really needs is the System.Core reference. Hope that's useful.
