I have a C#.net 2008 desktop application that uses some third party software. Since the third party software venfor went out of, I can not ask them any questions about their code.  Due to this fact, I have the following questions:

1. I know these third party components had to of been added as a reference. However, can you tell me if there is a way to tell how these third party components were added to the application? For example, could these components have been added as COM, .net components, and/or browse to a location?

2. If I want to remove any of these third party components from this visual studio 2008 C# desktop application, can you tell me how I wouldremove these items?
