Hi Moritz,
In Isolator version 7.4.1 we introduced a new feature - Plug-and-Play Profiling.
This feature allows you to use Isolator along with other profiler based tools without any additional configuration( as it was until this version). It means that you should be able to use Ncover as if your tests are written without Isolator.
I have some questions in order to better understand this issue:
1) What exactly is NCover UI? (Is it Ncover's Visual studio Interface?)
2) How Do you run the tests with Ncover UI? (Where do you go and what do you press?)
3) Do you have any special setup for Isolator in Ncover?
Looking forward to your reply.
