Method 'RouteCollection.get_AppendTrailingSlas

问题:

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.

回答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.

回答2:

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.

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.
