WPF Prism应用程序 - Automapper导致System.Core加载失败

Question

我有一个WPF 4.5 Prism项目，它可以正常工作，直到我添加Automapper 3.0。当我将Automapper添加到我的DAL以便从实体框架对象转换为DTO时，应用程序在运行时失败，似乎在创建shell之后立即执行。我在某处看到Automapper在某些情况下没有完全部署，因此我已将对Automapper和Automapper.Net4的引用添加到Shell项目中，以确保部署所有内容。

这是我收到的错误消息：

Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The system cannot find the file specified.

以下是我添加的导致异常的代码：

namespace DAL
{
[PartCreationPolicy(CreationPolicy.NonShared)]
[Export(typeof(ICampaignActionDataAccess))]
public class CampaignActionDataAccess : ICampaignActionDataAccess
{
    public CampaignActionDataAccess()
    {
        //if (Mapper.FindTypeMapFor<CampaignAction, CampaignActionDTO>() == null)
        //    Mapper.CreateMap<CampaignAction, CampaignActionDTO>();
        //if (Mapper.FindTypeMapFor<CampaignActionGroup, CampaignActionGroupDTO>() == null)
        //    Mapper.CreateMap<CampaignActionGroup, CampaignActionGroupDTO>();
        //if (Mapper.FindTypeMapFor<CampaignActionDescriptor, CampaignActionDescriptorDTO>() == null)
        //    Mapper.CreateMap<CampaignActionDescriptor, CampaignActionDescriptorDTO>();
    }

    public IEnumerable<CampaignActionDTO> GetAllActiveCampaignActions()
    {
        //using (var db = new CampaignActionEntities())
        //{
        //    var actions = (from ca in db.CampaignActions.Include(d => d.CampaignActionDescriptors)
        //                   where ca.IsValid == true
        //                   select ca).ToList();
        //    return Mapper.Map<IEnumerable<CampaignActionDTO>>(actions);
        //}
        throw new NotImplementedException();
    }
}

}
