Method 'RouteCollection.get_AppendTrailingSlash' not found when using Razor Url helpers in ASP.NET MVC 5 Mono

Question

I am creating an ASP.NET MVC 5 application in Mono (Ubuntu 14.4, Monodevelop 5.9, Mono JIT compiler version 4.0.1).

I see that some of the razor components are not recognized, eg:

@Url.Action

When I add this

<a title="Notifications" href="@Url.Action("_Listing","Home")"> Home </a>

I get this error:

System.MissingMethodException

Method 'RouteCollection.get_AppendTrailingSlash' not found.

System.Web.Mvc is referenced from the packages. Is there anything else which is required?

Update: I tried these solutions so far:

• Does the Razor View Engine work for Mono?

• Is it possible to use Razor 2.0 view engine under mono?

• http://www.davidloo.com/?p=479

• http://iws.io/walkthrough-porting-asp-net-mvc-website-to-mono-2-6-1-and-mysql-on-linux-apache-porting-to-mono-part-3-of-3/

It seems like it is a known issue but I strongly believe there shall be some hack for this to work. I tried using aspx engine also but no gain.

Do you get the same error if you move the @Url.Action into javascript, for example: location.href = '@Url.Action("_Listing", "Home")'; – Insectivore

Nope, it doesn't work . The same issue. – Meaningful

Answer 1

The latest news afaik is that Miguel rejected my minimal pull request last year but you can see at the bottom of that Pull Request that a couple of others have got builds on github which include this and more.

I can't see anyone's got a pull request accepted for mono mainline. The way forward I can see is if you know/can persuade someone on the Xamarin team to push this.

Or, helping with getting the now-open-sourced .Net code running on mono.

But https://github.com/gentoo/dotnet looks interesting: It has pulled this and some other MVC5 changes.

The fix for this is currently on Master. They expect it to be in the 4.3 release. Not sure when that is going to be however. – Hunks

As of right now, the only way to get around this is to build and install Mono from source from GitHub.

You can refer to the Xamarin Bugzilla issue: https://bugzilla.xamarin.com/show_bug.cgi?id=16475#c13

But, then, you might end up running into something else.... This doesn't seem to be a high-priority for the Mono guys; rather, the Xamarin/mobile story seems to gain the most attention.

Thanks @realistchuckle - I tried that as well. Doesn't seems to be working. I'm trying to make MVC 4 atleast to work using your blog but getting numerous issues. – Meaningful

Answer 3

The problem now seems to be resolved.

Meanwhile, I had used this simple hack: Instead of using ASP.NET MVC helpers, We can use basic HTML syntax like this:

For anchor like components:

<a href="~/ControllerName/ActionName"> Test </a>

For form like components:

    <form action="~/ControllerName/ActionName">
    <br>
    <input type="text" placeholder="Test"/>
    <br>
    <input type="submit" value="Submit"/>
    </form> 

Surely, it doesn't solve the bug but at least it can get ASP.NET MVC 5 project running on Mono.

Thanks to @teovankot for pointing this out.
