如下异常提示，我用的EF6.0. Entity和Map方式，将ASP.NET MVC托管到IIS下没有问题。但在Linux环境部署Jexus托管后，有时候会出现以下的问题。

异常如下：

5. 异常: Expression of type 'HanduRun.Application.Mapping.DeviceManage.RcdHistoryControlWordMap' cannot be used for parameter of type 'System.Data.Entity.ModelConfiguration.EntityTypeConfiguration`1[HanduRun.Application.Entity.MsManage.MsYjzbEntity]' of method 'System.Data.Entity.ModelConfiguration.Configuration.ConfigurationRegistrar Add[MsYjzbEntity](System.Data.Entity.ModelConfiguration.EntityTypeConfiguration`1[HanduRun.Application.Entity.MsManage.MsYjzbEntity])'
