Question

I have only tried this in single project areas. So if anyone tries this in a multi-project areas solution please let us know.

Area support was added to MVC2. However the views for your controllers have to be in your main Views folder. The solution I present here will allow you to keep your area specific views in each area. If your project is structured like below, with Blog being an area.

+ Areas          <-- folder
  + Blog         <-- folder
    + Views      <-- folder
      + Shared   <-- folder
      Index.aspx
      Create.aspx
      Edit.aspx
+ Content
+ Controllers
...
ViewEngine.cs

Add this code to the Application_Start method in Global.asax.cs. It will clear your current view engines and use our new ViewEngine instead.

// Area Aware View Engine
ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new AreaViewEngine());

Then create a file named ViewEngine.cs and add the code below.

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Web.Mvc;

namespace MyNamespace
{

    public class AreaViewEngine : WebFormViewEngine
    {
        public AreaViewEngine()
        {
            // {0} = View name
            // {1} = Controller name

            // Master Page locations
            MasterLocationFormats = new[] { "~/Views/{1}/{0}.master"
                                          , "~/Views/Shared/{0}.master"
                                          };

            // View locations
            ViewLocationFormats = new[] { "~/Views/{1}/{0}.aspx"
                                        , "~/Views/{1}/{0}.ascx"
                                        , "~/Views/Shared/{0}.aspx"
                                        , "~/Views/Shared/{0}.ascx"
                                        , "~/Areas/{1}/Views/{0}.aspx"
                                        , "~/Areas/{1}/Views/{0}.ascx"
                                        , "~/Areas/{1}/Views/Shared/{0}.aspx"
                                        , "~/Areas/{1}/Views/Shared/{0}.ascx"
                                        };

            // Partial view locations
            PartialViewLocationFormats = ViewLocationFormats;

        }

        protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
        {
            return new WebFormView(partialPath, null);
        }

        protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
        {
            return new WebFormView(viewPath, masterPath);
        }

    }   // End Class AreaViewEngine

}       // End Namespace    

This will find and use the views you have created in your areas.

This is one possible solution that allows me to keep views in the specified area. Does anyone else have a different, better, enhanced solution?

Thanks

This solution works well in Mvc2. It is not necessary in Mvc3.
