ATM I'm running it on xsp4 directly so I *think* any error would be displayed
on the terminal but I'll look into it. At the moment my gut tells me it's the
third part of the error message that applies: "or no view engine supports the
searched location". Maybe because it's an MVC5 file which apparently the
current release of Mono's System.Web.Mvc.dll doesn't support? Right now I'm
building the latest mono from git as I read somewhere that the
AppendTrailingSlash issue is fixed and it should run Microsoft's MVC5
assemblies.
Another hint that that may be the case is that I don't have the ViewBag
property on my controller class. I think earlier version used ViewState or
something like that. So after I fixed that my app is in effect an MVC3
application (except for the cshtml files).

I understand how they work, and I did had the copy local checked at that time,
but the point is that I'm referencing Mono's assembly and it's copying
Microsoft's. I think it's because MonoDevelop bundles Microsoft's assemblies
(either that or Microsoft's code built against a later version of Mono than
the current release). I did not look deep into this yet but it is obvious by
the fact that they reference the AppendTrailingSlash.
I also know that I should use the full path. The reason I did it is because
MonoDevelop doesn't list all GAC assemblies, apparently it's package oriented
and it's got a package called Mono but it doesn't include them all.

Really I don't NEED anything from that requires MCV 5. The only features that
my app uses at the moment is the view file format (I already fixed the ViewBag
issue). Really I'm just trying to catch up with MS technologies. I'm MS
certified developer but I haven't worked with it for several years (since
around the time .NET 3.0 came out) and I never looked into MVC before so I
decided to port an existing WebForms website (which runs on Linux) to the
latest MVC.
I will end up reverting to MVC 3 anyways since I don't want to run an unstable
mono on a live server but I do want a linux environment to play with MVC5
features and that's what this is about.
Thanks for the reply. I will post the outcome if it works with the latest
mono. Let me know if you have any other ideas.
