I separated out my models from my main ASP.net MVC3 app into a class library which is apart of the same solution as my project and is referenced into my project.
How ever the models in this class library (I copied the models folder over to the class library) are saying things like system.web.MVC or .Security or even System.Component.DataAnnotations do not exist.
So I assumed I could right click on references and click "Add reference" and find those .net libraries but alas they do not exist.
So how do I include them in? So I can use Data annotations, Security and (apparently) MVC?
It looks like you don't have ASP.NET MVC framework installed. If you have them installed, they should show up in your GAC (Global Assembly Cache) which your "reference explorer" pulls its dlls from. You can access the gac via C:\Windows\Assembly.
