Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Elmah.MVC issue


Locally - my MVC 4, asp.net, c# app runs fine on IIS 8 / Windows 8.

When deployed to Windows Server 2008, I get this error:

Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

and

[FileLoadException: Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)]

This happens if I select 'Only files needed to run this application' from the 'Items to deploy' drop down in project properties/package/publish web.

If I select 'all files in this project' it works fine.

I guess Elmah is reliant on an older version of MVC or something - how can I fix this without having to upload all the files?

Whats the best way to problem solve situations like this?

Thanks.


Solution

  • I had this exact same issue using MVC4 with Ninject built for .Net 4.5

    To fix this i had to add a binding redirect to my Web.config file: (at the end of the file, just before the </configuration> tag)

      <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
          <dependentAssembly>
            <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35"/>
            <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
          </dependentAssembly>
          <dependentAssembly>
            <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
            <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0"/>
          </dependentAssembly>
          <dependentAssembly>
            <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35"/>
            <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
          </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
        </assemblyBinding>
      </runtime>
    

    This forces the web server to use System.Web.Mvc 4.0.0.0 instead of an older version.
