Remove Trailing Slash in ASP.NET MVC 4 Route to Application Root

Question

In my ASP.NET MVC 4 application's RouteConfig file, I have registered the following default route:

routes.MapRoute("Default", "{controller}/{action}/{id}",
    new { controller = "home", action = "index", id = UrlParameter.Optional });

Now, in my Razor views, I want to generate a URL to my application's root like that:

<a href="@Url.Action("index", "home")">Home</a>

The generated URL includes a trailing slash; clicking the link thus opens the page localhost/IISApplicationName/. However, I want the URL not to contain the trailing slash so that the URL is localhost/IISApplicationName. Generating routes for other actions, such as /Account/Login, does not create URLs with trailing slashes — it's just about the route linking to my application's root.

Is there any way to prevent ASP.NET MVC routing from appending the trailing slash to the above route?

(I know that I can redirect from the URL including the slash to the one without it, but I'd rather have routing generate the correct route URL in the first place.)

I recommend URL Rwrite Outbounds rules.

Creating Outbound Rules for URL Rewrite Module : URL Rewrite Module 2 : URL Rewrite Module : The Official Microsoft IIS Site

Sample config:

    <rewrite>
        <outboundRules>
            <rule name="RewriteSlash">
                <match filterByTags="A" pattern="^/IISApplicationName/$" />
                <action type="Rewrite" value="/IISApplicationName" />
            </rule>
        </outboundRules>
    </rewrite>
