I have been operating with ASP.NET MVC for some time and yet I still had trouble making an attempt to get a URL in a view. URL generation is particularly important for ASP.NET MVC as a result of it uses a routing engine to map URLs to code. If we hard code a URL then we lose the ability to later vary our routing scheme. I have found 2 ways that currently (ASP.NET MVC preview 2) work to generate URLs in a view. the first uses the GetVirtualPath method and seems overly complicated - thus I wrapped it in a global helper:

public static string GenerateUrl(HttpContext context, RouteValueDictionary routeValues)
    {
        return RouteTable.Routes.GetVirtualPath(
            new RequestContext(new HttpContextWrapper2(context), new RouteData()),
            routeValues).ToString();
    }

But then I found that I could achieve a similar result additional simply using UrlHelper, accessible via the URL property of the view.
// link to a controller
Url.Action("Home");

// link to an action
Url.Action("Home", "Index");

// link to an action and send parameters
Url.Action("Edit", "Product", new RouteValueDictionary(new { id = p.Id }));

Or, if you want the url for a hyperlink you can get that in one step using the ActionLink method on the Html property:
Html.ActionLink<HomeController>(c => c.Index(),"Home")

So I no longer see a need for my GenerateUrl method and have removed it from my helper. All of this would be much easier if there was some documentation. Im sure there is a better way so if you can think of an improvement please leave it in the comments.
