Hot Reload seems not to work properly for ASP.NET Core

Error:

How to replicate: Hot Reload a change, execute the change couple of times.

Came across this issue when searching for a solution to the same problem I am facing, but not using coreddd.

It seems that this is an issue with nhibernate itself, and not specifically with this library

That's my feeling as well. Wanted to reproduce it purely using NHibernate and not CoreDdd, but have no time to do that. Hopefully I will do it at some point in the future 🙂
