I recently moved from my old dev environment running VS 2015, .Net 4.5.1 on Windows 8.1 to a new environment running VS 2017, .Net 4.6.2 on Windows 10.
Previously I was able to call update-database -script from the package manager console with no problem. Though since the move I am struck with this strange error.
Has anyone else run into it, and if do you have a fix?

I see that @lincolnzocateli makes mention of this problem here https://github.com/aspnet/EntityFramework/issues/7031 and then here https://github.com/aspnet/EntityFramework6/issues/156 but the solution is rather vague.
