Add ExcludeFromMigrations option

Feature Request:

Enable use of “ExcludeFromMigrations()”.

A sample of the output code is shown below. For full support, I think it would need to be in the GUI as a checkbox on the Advanced options.

Code

The output would look like this:

modelBuilder.Entity<MyTable>(entity =>
        {
            ...
            entity.ToTable("MyTable", e => e.ExcludeFromMigrations());
            ...
         }

Background

In my client’s environment only allows migrations in the dev environment. When EFCore projects are migrated to other platforms where migrations are not allowed, we’re seeing errors where the [dbo].[__ConversionHistory] does not exist. The “ExcludeFromMigrations()” helps eliminate the error, while allowing test scenarios to create a DB as needed. E.G.: SQLite In-memory db.

Got it, but mixing migrations and db first is very uncommon, and you are the first and only person asking for this. And there is a simple way to do this in your own code.

I know you can’t fix process issues with technology. This is a long-running task of mine.

I need to better understand your code. It’s more a question of time for me. If I can figure it out, I can add a PR then we’d both be happy.

As for a single use-case, I don’t fully agree. I have worked with several clients/employers that are very permissive in the dev environment and very restrictive in the production environment. I can’t be the only one to have seen this scenario in the real world. I might be the first to raise it with you but… shrug.

Thanks for answering my questions. As I said, I need to learn more about your code to be more articulate and/or create a PR for your review. Thanks again.
