PMC Tools: Exception calling "AddFromFile"

[ajcvickers]

From VS Feedback:

I just upgraded my solution to .net core 2.0 and also find Entity Framework migrations to be working very inconsistently in the package manager.

I tend to get the following error on "add-migrations"

"add-migration : Exception calling "AddFromFile" with "1" argument(s): "'basePath' cannot be an empty string ("") or start with the null character."

• Add-Migration : Exception calling “AddFromFile” with “1” argument(s): “'basePath' cannot be an empty string (”")

This made me curious. We would throw above exception when the generated file is essentially null coming out of reveng or add-migration. I am trying different things to achieve that but so far all I got is VS crash.

I can't repro this. If anyone has a solution that consistently fails with this error, please let us know so we can investigate further.
