SSDT, Publishing, and Referenced Databases

Had this catch me today in a series of databases that all work together. In order to resolve all of the cross-database dependencies, I've added database references to the project. That takes care of all of the "Database.dbo.Object" references outside of the database. The problem is that within the current database, you will get errors without that reference defined.

In my haste to get the projects working, I added a database reference to the current project. I would build my project and reference the generated *.dacpac files when publishing. The problem is that every time I built my project, the referenced dacpac file would overwrite the generated dacpac file.

Results from this problem - I noticed that my "DeployType" variable wasn't referenced anywhere, which struck me as odd because I use it in my Pre and Post Deploy scripts. I also started noticing that my dacpac file in my build folder was out of date, even after a successful build.

Workaround - do what I have done otherwise - replace all instances of CurrentDatabaseName.dbo. with just dbo. in all SQL files in the project.  This also includes the various forms that this can take:

Once I replaced all of those references and rebuilt the project successfully, my publish actions started working again. My Deploy scripts were included. I didn't get mysterious warnings about my variables not existing.

There may be a different way to work around self-referenced database objects within SSDT, but until I come across that, the workaround is to remove them from the code and not to just add a reference to the current database through a dacpac file.
