Question
I'm running default api core project on Visual studio 2017 with docker support and
I got this error everytime I run the command add-migration -name name
add-migration : Cannot bind argument to parameter 'Path' because it is an empty string. At line:1 char:1 + add-migration + ~~~~~~~~~~~~~ + CategoryInfo : InvalidData: (:) [Add-Migration], ParameterBindingValidationException + FullyQualifiedErrorId : ParameterArgumentValidationErrorEmptyStringNotAllowed,Add-Migration
PS : This command works without docker support, but return this error when I add docker support
Accepted Answer
It looks like you're hitting issue #7540. For now, put your project on a "physical" drive instead of a network file share. (Scratch that. You're using the PMC commands.)
You're probably hitting issue #7439. Make sure your app is selected as the startup project (or use the -StartupProject parameter) when running the commands.

It would be interesting to know with which version of Entity Framework this error occurred. I had the same error with EF 6.3.0 and I am not using docker at all.
The solution for me was to go back to version 6.2.0 and create the migration with it.
