Cannot find the derived classes in different namespaces

[scott-xu]

Describe the bug
No type inheriting from IJob was found that matches the "*" filter.

To Reproduce

.Roots<IJob>()

DIE016: No type inheriting from Quartz.IJob was found that matches the "*" filter.

A workaround is to add the using statement, so that all implementations under that namespace are recognized.

using My.Service.Jobs;

Expected behavior
Should be able to find all implementations in current project no matter which namespace they are under.

Additional context
BTW, if it is interface, the word should be "implementation" rather than "inheriting" in the error message.
