ASP.Net MVC Providing bolt-on functionality to existing web app

Is it possible to have a ASP.Net MVC application as a core application and then have a seperate project containing, models, controllers and views that will compile and then copy to the core app bin directory so the core app picks this extra functionality up?

I hope you can see what I'm trying to suggest. The methods I have mentioned may not be correct but essentially have a co开发者_JAVA百科re web app with pre-determined functionality and then on occasion add extra functionality via another project in the solution

UPDATE: Now using ASP.Net MVC 3 and reading this post, the author of Portable Areas seems to think there is another way which I dont understand fully. How can achieve what I want in MVC 3?

Yes, you may take a look at MVCContrib Portable Areas. It uses embedded views.
