Thank you for your feedback!
Most probably some process locks the assembly. You can try to find the offending process using Process Explorer
. That will give us more information about the problem.
Could you please give us more information about your test project? Which testing framework do you use? Could you please try to isolate the problem in a simple self-contained solution and send it over so we can investigate on our side? You can open a support ticket and attach the project there.
If you have other problems or questions, please don't hesitate to write back!
