asp.net - Is it possible to access MVC Views located in another project?

Question

I want to separate my MVC project into several projects

So first of all, I've created two projects Front and Views

The Front project is a web application that contains controllers and models

The Views project is a class library project that will contains only the views

My question is how can I make controllers call views located in the Views project

I have controllers like this one:

public ActionResult Default()
        {
            return this.View();
        }

For including controllers you need to change your route registrations to tell them where to look for the controllers:

routes.MapRoute(name: "Default", url: "{controller}/{action}/{id}",
                namespaces: new[] {"[Namespace of the Project that contains your controllers]"},
                defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional});

For including views, create custom ViewEngine:

public class CustomViewEngine: RazorViewEngine
{
    public CustomViewEngine()
    {
        MasterLocationFormats = new string[]
        {
            "~/bin/Views/{1}/{0}.cshtml",
            "~/bin/Views/{1}/{0}.vbhtml",
            "~/bin/Views/Shared/{0}.cshtml",
            "~/bin/Views/Shared/{0}.vbhtml"

        };
        ViewLocationFormats = new string[]
        {
             "~/bin/Areas/{2}/Views/{1}/{0}.cshtml",
             "~/bin/Areas/{2}/Views/{1}/{0}.vbhtml",
             "~/bin/Areas/{2}/Views/Shared/{0}.cshtml",
             "~/bin/Areas/{2}/Views/Shared/{0}.vbhtml"
        };
        .
        .
        .
    }
}
protected void Application_Start()
{
    ViewEngines.Engines.Add(new CustomViewEngine());

For more information look at the default implementation of RazorViewEngin.
