stashbox: variable '' of type 'System.IServiceProvider' referenced from scope '', but it is not defined
Hi am using stashbox with aspnet core 2.2 and Hangfire.
It is a multi tenant solution, where I spawn one hangfire instance for each tenant, and I hand each hangfire instance their own child container with their own specific registrations.
However when the hangfire server tries to start a job, and resolve a service, I get the following exception.
System.InvalidOperationException: variable '' of type 'System.IServiceProvider' referenced from scope '', but it is not defined

Ah, I see, thanks for your effort anyway, without this issue, those problems would have stayed in the code for a long time I think. And thank you in advance for spending your own time recreating that exception!
Yes, what you described was the main goal of the child container feature, and also it should work now in that way if I remember correctly. To be honest, except the tests I never used this feature in real projects and never got issues about it until now, so I’m really glad because this is an opportunity to make it more usable! Please let me verify that it works as you explained and if not I’ll make the necessary changes!
