ASP.NET MVC - Pluggable application modules/components/area/features - Publishing/Deployment

Hi,

I and working on a large ASP.NET MVC application with multiple modules. I am using AREAS for each module. I need to split share some common functionality across all the modules. Also I need to be able to deploy any module without affecting other modules.

I tried to follow this link below

Is this the best approach ? I am having issues publishing this with each AREA separately to Web Server. 

Can any one suggest better approach ? OR a solution for easy deployment of each Area?

Thanks,

Srik.
