After modifying an EDMX in Visual Studio 2019, it saves the EDMX properly but does not generate the C# files.
This is a database first functionality, is there a new trick in VS2019 to actually generate the C# files on save?
I was going to write a feedback to Microsoft but the same question is asked on their network. The issue was
VS 2019 Preview2-Preview 4.2 after saving EDMX code is not generated
It is marked as resolved for VS2019 16.1
https://github.com/aspnet/EntityFramework6/issues/705
It is also mentioned in the bug that you may run the custom tools manually on all the EDMX, and *.tt files to generate your templates. And this works.
