Design Meeting Notes (October 28, 2015)

DNX Commands and Startup Projects

The original design of the DNX commands was that you would invoke it on the target project (e.g. MyApp.Data) and pass in the startup project (e.g. MyApp) using the --startupProject. However, DNX is not able to load an assembly that isn't referenced by the current project, and referencing it would result in a circular dependency since the reference needs to go the other direction (e.g. MyApp needs to reference MyApp.Data).

In order to fix this, we're swapping the two projects. The commands will now need to be invoked on the startup project, and a --targetProject option will be provided.

For example, to add a migration you would use the following commands.

cd src\MyApp
dnx ef migrations add MyMigration --targetProject MyApp.Data

This will add a new migration to the MyApp.Data project using MyApp as the startup project.
