Entity Framework inheritance : table per concrete class (DB first)

Question

I'm new to Entity Framework, I need to implement the table per class inheritance strategy. This followed the steps explained in this tutorial

https://www.packtpub.com/books/content/entity-framework-db-first-%E2%80%93-inheritance-relationships-between-entities

But I get this error:

employee and vendor entity are not mapped

I found this article not well detailed. Can you give me more explanations?

Thanks to everyone
