I've been trying to find information on this everywhere for quite some time now. I want to build DLL plugins for my application, but don't want to implement them at basic run time. I want the user to be able to import them through an open file dialog. Any help on this topic is appreciated.

I'd suggest you start by getting familiar with application domains and the AppDomain class. There are various "how to" articles linked in both of those pages that should get you going.
