How to slip an Oracle database into a ready-made C# application?

Question

Oracle

Greetings.
There is a ready-made, functioning C # desktop application. There was a need to make friends with the Oracle database, which will contain identical data. In the application, work with the database is built on the Entity Framework.
How to make such an application friends with Oracle?
The visual studio project of this application has been gone for a long time, we need to somehow get out :)
Thank you very much in advance for the advice!
