EntityFramework Core doesn't use the "EDMX" data model designers, it is purely code-first.
If you want to scaffold a database context from an existing database or create a new model and use migrations to create and update databases, you could see this page. https://learn.microsoft.com/en-us/aspnet/core/data/ef-rp/intro?view=aspnetcore-6.0&tabs=visual-studio
