Scaffold-DbContext throw ArgumentNullException

I get the following exception when I try to scaffold one of our databases.

I successfully scaffolded one of our databases so I'm sure I'm using the scaffold command properly. Also, I can access the database using the connection string I entered on the Scaffold-DbContext command.



I installed the following packages:



install-package microsoft.entityframeworkcore.sqlserver
install-package microsoft.entityframeworkcore.tools


Using .NET Core Console App 2.1 on Windows 10.



Not sure if this is related but I get the following message when I try to expand the Database Diagrams in ssms. (I don't get this message on the other database that I successfully scaffolded)

  • You could consider creating the DbContext and model classes manually. I've had similar trouble once or twice using the scaffold command so I don't use it anymore. It's less work doing it by hand than trying to figure out what's wrong.
