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

Question

I installed the nuget package for MvcMailer, found here . Although it didn't (as it says in the tutorial it will) add smtp configuration to web.config, I found the correct smtp configuration here .

I'm using MVC4 in VS2010.

When I compile, I get the following error in the the error list:

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

I also get the following warning:

Warning 2 Found conflicts between different versions of the same dependent assembly. MVCMusicStore

I removed the MvcMailer reference and added it again, but it didn't resolve the issue.

Help would be much appreciated.

Answer 1

I'm using Mvc 4, and was installing MvcMailer via the package manager with the following:

install-package MvcMailer

Because I'm using Mvc 4, the following should be used:

install-package MvcMailer3

This has resolved the issue.
