Deploying ASP.NET MVC Project

Question

I'm trying to deploy the default MVC project (from Visual Studio 2013) onto a remote server. They require the program to be running in Medium Trust mode, which I am having issues with. I've added <trust level="Medium" originUrl="" /> to the <system.web> section of Web.config. Then when I try to run the program on my local machine, a SecurityException is thrown by this line:

@Html.ActionLink("Application name", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })

This is located in the _Layout.cshtml file, which I haven't modified from the generated template (when you create a new MVC 5 project).

My question is: what do I need to do to get my project to run in Medium Trust mode?

Have a look at this answer. It also appears that the [assembly: AllowPartiallyTrustedCallers] attribute has been removed in MVC5 which is probably the cause of the exception in the html helper — user3559349

MS have also stated in known issues that "ASP.NET MVC 5 no longer supports partial trust...." (perhaps time for a new hosting provider?) — user3559349

Sigh, thanks. You're the first person who's been able to give me that reason. If you post that as an answer I'll mark it as the answer. — Mr_Bean

The current versions of ASP.NET now only support full trust. MS have stated in Release Notes: Known Issues that:

ASP.NET MVC 5 no longer supports partial trust....

In particular the [assembly: AllowPartiallyTrustedCallers] attribute has been removed from the source code. You can read more about ASP.NET's official position in Levi's answer to is-trying-to-develop-for-medium-trust-a-lost-cause, which also includes further links to why support has been removed.
