I've successfully compiled Objective-C Binding projects in Visual Studio but Intellisense/Object Browser do not pick up any of the symbols making it impossible to use Visual Studio with these projects.
I have checked this issue and noticed that "Intellisense/Object Browser" is not working properly for iOS "Binding Project", while it work fine for iOS "Library Project" and iPhone "Empty Project" and others iOS project.

This is approximately a duplicate of bug #16555.
See in particular:
In short, Objective-C binding projects are only supported in Xamarin Studio on Mac, and not yet in Visual Studio . The template project that's included with the Xamarin.iOS Visual Studio extension is misleadingly just a plain iOS _library_ project, and is slated to be removed ASAP .

The reason Intellisense doesn't work is that the resulting `.dll` is empty. That is, compiled library does not contain any types. This happens because the "ObjcBindingApiDefinition" Build Action is currently equivalent to a Build Action of "None".
Thanks for the report!
What Brendan states is true: in VS up until 2013 only files marked as Compile will have C# intellisense. This has been solved in 2015 and our cs files in binding projects have intellisense. Marking as Upstream because there is not much we can do about it. The only workaround we have is to set it as Compile while editing, which leads to a looooot of bugs.
I'm using VS 2015 and I still don't get intellisense for an iOS Binding Project. Do you know if this is still an issue?
Any news on Jeremys question regarding VS 2015? Having the same issue. Only "workaround" is to not use project references and instead use an assembly reference to output-dll of the binding project.
Just in case anyone is using this workaround: It will break Resharper-functionality for the types within the binding project. To resolve this you have to move the binding project into a separate solution.
