When attempting to create a new Entity Framework EF EDMX Model for an existing Oracle database using Visual Studio 2017's Entity Data Model wizard I receive a popup stating
**Operation is not valid due to the current state of the object.**
In the previous screen I am able to attach to the Oracle database/service via `Test Connection` but after I select to accept the settings, the dialog closes and this error stops me from being able to go farther and actually select tables and what from my database.
What can be done?
This is relatively a new PC with Windows 10 setup with no other Oracle installs except the current ones listed below. VS2017 is the latest Enterprise edition Version of 15.8.9.
Versions
ODT for VS2017 183000
