profiling session has already been launched

I'm trying to profile 2 apps on my win 10 server. One is windows service and the other is stand alone app that call the service.

When I'm attaching to anyone of them I cannot attach to the other so I cannot profile both of them together.

 

Any reason for that ? What am I doing wrong?

Hi,

We do not recommend to profile several apps simultaneously because profiling of an app can affect the performance of another app and vice versa, so time values in performance snapshots taken from both apps may be incorrect. But if you want to try - you can: just start profiling from another instance of dotTrace started under elevated account (right click on the dotTrace icon in the taskbar -> right click on JetBrains dotTrace... title -> Run as administrator). Also, you can run the second profiling session from Visual Studio integration.
