Getting Started with Plugins/Interceptors

Hello all.

I'm getting started on creating custom Interceptors, and I'm very green in this area (I'm a SQL developer with a tiny bit of C# in my background, but I'm really excited to have a chance to work on interceptors).  I've watched the webinar and created my "Hello World" plugin in Visual Studio 2012.  Now I want to try my hand at something real, so I'd like to check out some examples and get an idea of what makes them tick.  I copied the Tessitura.Services.Plugin.Examples.dll but I don't know how to crack it open and see what's defined within it.

A co-worker suggested trying to get a project in which the .dll is used, saying that's probably a better way to get at it.  Is that the right way to go about this?  If so, how can I get that?

Any help would be greatly appreciated.

Thanks!

Nathan
