Tried to run the migrator against;
"Default": "Server(localdb)\mssqllocaldb;Database=ProjectName;Trusted_Connection=True;MultipleActiveResultSets=true"
But received the following error. I don't have SQL so I spun up a quick db in Azure, changed my connection string and re-ran the migrator, same issue.
Any suggestions? Thanks.

your connection string is incorrect. it's for self hosted mssql database. chose one of those :
- use the correct local connection string
- install an sql server express (FREE but size limitation)
- instan an sql server full (FREE for development only)
- put the correct connection string from azure

Thanks @daws. I faced a similar problem with azure some time ago and as far as I remember azure puts some extra parameters to connection strings that it gaves and those parameters might cause connection problems.
You can try to remove "MultipleActiveResultSets=true" first and give it a try. You can also try your connection string with SQL Server Management Studio or a similar tool that you can test the connection string.
