title: Won't compile after installing: Mcv.Mailer version 1.0 uses Mvc version 4.0, which has higher version than referenced assembly Mvc version 3.0
body: <p>I installed the nuget package for MvcMailer, found <a href="https://github.com/smsohan/MvcMailer/wiki/MvcMailer-Step-by-Step-Guide" rel="nofollow">here</a>. Although it didn't (as it says in the tutorial it will) add smtp configuration to web.config, I found the correct smtp configuration <a href="http://www.hanselman.com/blog/NuGetPackageOfTheWeek2MvcMailerSendsMailsWithASPNETMVCRazorViewsAndScaffolding.aspx" rel="nofollow">here</a>.</p>
  
  <p>I'm using MVC4 in VS2010.</p>
  
  <p>When I compile, I get the following error in the the error list:</p>
  
  <blockquote>
    <p>Error 1   Assembly 'Mvc.Mailer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'   c:\Users\Home\Desktop\MVCMusicStore - Copy\packages\MvcMailer.4.0\lib\40\Mvc.Mailer.dll MVCMusicStore</p>
  </blockquote>
  
  <p>I also get the following warning:</p>
  
  <blockquote>
    <p>Warning   2   Found conflicts between different versions of the same dependent assembly.  MVCMusicStore</p>
  </blockquote>
  
  <p>I removed the MvcMailer reference and added it again, but it didn't resolve the issue.</p>
  
  <p>Help would be much appreciated.</p>
