I've tried manually creating the directory in the target path provided in the stack trace with no luck. It looks like it's missing the actual running env directory? Its targeting the path where my solution file is located, not where my source code is (where the actual wwwroot folder is).

@Ryan-J-D Did you find any workaround for this? Even I'm facing the same issue.

Seems to be a AspNetCore 3.1 issue, apparently this library only works on 2.0 from what I've seen online.

I used this instead: https://www.devart.com/entitydeveloper/

Wow, it's been a while. This error means that frontend app is not built yet. Building frontend app creates that directory and puts assets there. I will add an exception rethrow with this hint.

Can you provide instructions how to build the frontend into the readme?
