I'm having some trouble with Microsoft .NET Entity Framework Core. I am converting a project from database first to code first. The project also needs to be uplifted from .NET Framework v4.8 to .NET 8 and it is moving from EF6 to EF Core. I ran some kind of a project upgrade thing to create 2 new projects - the data model and the forms/UI stuff. I also created a completely separate solution and installed EF Core Power Tools. In this new project I requested that my database be Reverse Engineered. With the classes that were produced I went back to my new project folders and added the data entities, fixed up the namespace and so on.
