Oracle and entity framework in visual studio

I have installed all of the oracle software and databases and so on to work with .Net and Visual Studio 2010. There is a tutorial on the oracle website that describes how to work with the entity framework and oracle, yet.. when I am going through the entity data model wizard in visual studio 2010, I get to "choose your data connection", and the only thing there is "ApplicationServices". Yet in the 开发者_如何学Pythontutorial on oracles website, there is an option for the oracle database? My oracle database is working and viewable from the server explorer... I have tried to edit web.config to add some kind of entry but that seems to have failed.

Did you install an EF provider for Oracle first? Oracle has a beta provider, and there are third-party providers (e.g., from Devart and others) as well.
