Efcore: Question: Generate migrations from code.

[alexdrl]

Hello, I'm trying to create a console app that tries to generate the migration code and detects if there are some operations that will be created in the generated code.

Ideally, if the dotnet ef migrations add <MigrationName> --json command would output the number of operations generated, that would be enough. A public API which returns a ReadOnlyList<MigrationOperation> like is passed to the CSharpMigrationOperationGenerator also will work. Is there some public API that I am missing? I am trying to fiddle with Microsoft.EntityFrameworkCore.Design.OperationExecutor, but the API seems too hard to use, and I am getting an error which says that the assembly is not found. I am trying to pass the same parameters as dotnet ef.

Any idea?

See this line in the database error page. It determines if there are any changes between the last migration and the current model.
