I was trying to deploy .NET 4.5 MVC4 project to the Mono 3.2 XSP and got exception.

Software:

  • Ubuntu Linux 13.04
  • Mono 3.2.1 compiled from sources
  • XSP4 3.0.11 compiled from sources

    • Exception text: 

    CS1701: Warning as Error: Assuming assembly reference `System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' matches assembly `System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. You may need to supply runtime policy

    Stack trace:

at System.Web.HttpApplicationFactory.InitType (System.Web.HttpContext context) [0x00000] in <filename unknown>:0

    Anybody solved it? How to get rid of it?

    I've found that the only way of getting an MVC3 project working on Mono was by copying some of the Microsoft assemblies to the Mono project, such as (if using Razor):

    • System.Web.Mvc
    • System.Web.Razor
    • System.Web.Helpers
    • System.Web.WebPages.Deployment
    • System.Web.WebPages
    • System.Web.WebPages.Razor

    Being you're using MVC4 it'll probably be something along the same lines - it's what the exception seems to be hinting (its seeing version 1 and expecting 4). Chances are you'll need different or additional assemblies to these. Have a look here, you might find some additional help.

    Also, .NET 4.5 is still not fully supported on Mono (no async on MVC4). Expect to find other problems there.
