Question

I am only using RazorViewEngine on one of my ASP.NET MVC 3 applications and I cleared Web Forms view engine out with following code inside Application_Start method of my Global.asax.cs file

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new RazorViewEngine());

I decided to see something solid so that I could be satisfied with this two-line-code-effort and I try to render a partial view which does not exist and I got this result :

The partial view ‘_ResortMapPartialView’ was not found or no view
engine supports the searched locations. The following locations were
searched:
~/Areas/Accommodation/Views/resort/_ResortMapPartialView.cshtml
~/Areas/Accommodation/Views/resort/_ResortMapPartialView.vbhtml
~/Areas/Accommodation/Views/Shared/_ResortMapPartialView.cshtml
~/Areas/Accommodation/Views/Shared/_ResortMapPartialView.vbhtml
~/Views/resort/_ResortMapPartialView.cshtml
~/Views/resort/_ResortMapPartialView.vbhtml
~/Views/Shared/_ResortMapPartialView.cshtml
~/Views/Shared/_ResortMapPartialView.vbhtml

It looks a little better. Now it looks for less items than before. But still the files with .vbhtml extensions are making me unconformable.

The question is that : How can we get rid of them?

Answer 1

My suggestion would be to override the RazorViewEngine definitions for the following to only include cshtml files.

• AreaViewLocationFormats
• AreaMasterLocationFormats
• AreaPartialViewLocationFormats
• ViewLocationFormats
• MasterLocationFormats
• PartialViewLocationFormats
• FileExtensions

An brief example:

public class CSHtmlViewEngine: RazorViewEngine
{
    public CSHtmlViewEngine()
    {
        base.AreaViewLocationFormats=
            new string[]
                {
                    "~/Views/{1}/{0}.cshtml",
                    "~/Views/Shared/{0}.cshtml"
                };

        base.AreaPartialViewLocationFormats =
            new string[]
                {
                    "~/Areas/{2}/Views/{1}/{0}.cshtml",
                    "~/Areas/{2}/Views/Shared/{0}.cshtml",
                };

   // All the other LocationFormats listed above will also need to be amended
   // Don't forget the FileExtensions array
   }

}

See my answer which talks about overriding these values. The same principle applies. You will need to register this modified ViewEngine (CSHtmlViewEngine) in the ApplicationStart method

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new CSHtmlViewEngine());
