Hello

I'm using nopCommerce long..

but since I have included in the project all the plug-in I have these errors ... why?

Error  1  The type or namespace name 'AutoMapper' could not be found (are you missing a using directive or an assembly reference?)  ...\Presentation\Nop.Web\Administration\MappingExtensions.cs  1  7  Nop.Web


Error  2  The type or namespace name 'AutoMapper' could not be found (are you missing a using directive or an assembly reference?)  ...\Presentation\Nop.Web\Administration\Infrastructure\AutoMapperStartupTask.cs  1  7  Nop.Web
