I have previous experience getting MS SQL Server to work with Entity Framework 6, and ASP.NET 4.5.2 Framework. It works great! However, when I try the same thing with the Oracle Managed Data Access Client, I have not been able to get it to work. These are the steps I have been following:
- Right click on the Models folder and pick Add ADO.NET Entity Data Model.
- Choose model contents: Empty EF Designer model. It creates the Model1.edmx file.
- Right click in the design space of the EDMX file, choose update model from database.
- Choose your data connection

This is where it fails. I briefly see this screen of the wizard, but then it disappears and nothing else happens.

I have tried it several times and always get the same results. I have seen similar posts on Stack Exchange, but they come with answers saying the Microsoft knows about it and will fix it. I am using Visual Studio 2022, so I thought it would be working by now.
