I am volunteer in a one project. We develop ASP.NET MVC Core app and we updated project to .NET 7.0. From this moment app works fine all the time, but I can't view edmx file. Is a way edit edmx without edit edmx in XML?
I tried add DbSet to DbContext, but this not work. Like i said - i can work on existing tables.
You need to keep a .NET Framework project in your solution for the .edmx file.
