DotTrace error after clicking Get Snapshot And Wait, unknown PDB info signature


I am trying to profile my web application which is running under IIS with DotTrace from inside visual studio. I start the profiling session from inside visualstudio using the "Run Startup Configuration Performance Profiling" button. When I press the Get Snapshot and Wait button I get the following error.

Unknown PDB info signature

Any help would be greatly appreciated. 

Thanks, Ryan.


Hi Ryan!

What version of dotTrace do you use?


Hi Konstantin,


I'm using dotTrace 10.


Thanks, Ryan.




Could you please install the latest EAP build ( ) and check if the issue persist? If it persists, could you please create a support ticket ("Submit a request" button in the upper right corner) and attach full error description from the profiling controller to it?
