I encountered also error during discovery.

Hi!

The "Could not load file or assembly" issue is quite challenging to resolve, as it heavily depends on the local machine and the specific project being used. There are numerous reports of this problem.

If you believe addressing this issue is a high priority compared to other features, please consider upvoting the discussion at https://github.com/orgs/reqnroll/discussions/977.
